I have worked as an architect in HCLS technology for 10 years with Google and AWS.

Listening to you stitch all the technology and innovation together, moving from the information world to the physical world, as a patient, almost brought me to tears.

You said this will be the standard of care in 30-years, but the capability is here today. Listening to your recording is a profound moment in my life.

Thank you for sharing your journey.

Sid, Thank you for funding Arden Bio. Rheumatology patients and their clinicians are often left to throwing darts from afar, in series and often with significant & permanent function loss with each dart. Moreover, proper care of refractory rare diseases is not something that insurance funds: my otherwise excellent coverage expressly denies "investigatory" treatments, for example. As a small fiber neuropathic vasculitus patient with secondary Sjögren's I really look forward to progress in this field, it cannot happen soon enough. Best of luck in your own care and profile. - Clark

All of these companies (including the Even One Ventures and Open Core Ventures ones) have CEOs who run them day to day. I try to help with positioning and setting ambitious goals. Y Combinator really opened my eyes to how helpful setting clear and hard to reach goals is.

by sytse

3/29/2026 at 3:42:20 AM

thanks Sid! i think a lot of people incl myself aspire to be where you are - I have effectively 3 businesses and have only hired one GM (on track to be CEO), but the other 2 I am effectively CEOing. yet I have this maybe misguided asian/protestant theory that I haven't "earned the right" to multicompany yet, and if i take my hands off the wheel the whole thing might be at risk. With GitLab obviously you were driving for many years and it feels like only with your cancer diagnosis you started letting go.

no question in there, just a comment, love your openness and giving back to the community, wish you full success and recovery.

I wish you the best, my brother-in-law (also a close friend) lost his fight against cancer in 2019, it changed my perception of life forever. What we live is a bit like how we die, I had some of the best moments with him while he was more aware than myself about how we are all going to die, he changed my perception of caring much more about the uniqueness and the present moment. One of my favorite quotes is from Buckminster Fuller, "You belong to the Universe. Your significance will remain forever obscure to you ... (see full quote on Wikipedia)". Thank you so much for all the creation you have done in this world Sid, just for Gitlab it's plenty. I am a long time & very satisfied Gitlab customer, I switched a long time ago for its superior CI/CD integration and its super inspiring handbook. Another favorite quote is actually from you ... "My reasoning was I got to tell everyone what I do, and I want it to be a really good story." Lately I fundamentally changed my perception, the most important computer of all is the planet Earth, you seem to be aligned with this vision as well, correct me if my perception is wrong. I hope you keep going on with all those beautiful stories, we are lucky to have you with us.

Full quote from Fuller for others

> You do not have the right to eliminate yourself, you do not belong to you. You belong to the universe. The significance of you will forever remain obscure to you, but you may assume that you are fulfilling your significance if you apply yourself to converting all your experience to highest advantage of others. You and all men are here for the sake of other men.

Love how you approached and presented this. The data vis on https://osteosarc.com/ is outstanding; such good explorability (is this some open source framework?)

I do have concerns regarding the proposals for scaling personalized medicine. They mostly boil down to "how do you scale the skill set required to operate in high-noise-low-signal domains". In my experience, these are places where poor data/incentives/critical-thinking can easily overshadow the signal; e.g., compelling stories outnumber correct stories.

There seems to be a trade-off: you can walk a bit further than others by keeping the probability distributions for low-quality results in your head, but go too far and everything starts getting overwhelmed by noise. It seems like the FDA's heavy gatekeeping is one way to solve this problem. If you forgo that gatekeeping, then you probably need to deal with the cascading quality issues that result.

Personalized treatments will probably be much harder to evaluate. At least a black-box algorithm that maps `situation → suggested treatment` can have statistics applied to it. But how do you evaluate "individuals made their own decision; here's the list of `situation × outcome`"? Or is the idea that there's currently a wealth of good-solutions, and that we should be relaxing regulations for a while?

Or perhaps we just want to push the regulator burden from "before small trials" to "before medium trials"? Then, these will be treated as case studies: good for experts to pull ideas from, but not high quality evidence for proving anything the third parties? I notice that your diagnostics were numerous, but the treatments were sparse and more sequential than parallel. If that's the norm, then maybe fairly usable data will emerge.

Or do people just have a moral right to seek out their own treatment, regardless of footguns that may be lying in wait? For myself and my loved ones battling cancer, I deeply agree with these:

> Maximize survival instead of the current practice of minimizing liability to the practitioner

> Parallel treatments wherever reasonable, we don't need to know what cured you

But I'm also glad that daily medical decisions are highly standardized and quality-controlled. It makes it easier to trust my doctor (or my loved ones' doctors) without independently investigating each recommendation.

How do you deal with setbacks both in work and life, and show resilience and belief you can find a solution? Is this innate or something you worked on? Also, are there things you think are impossible for you to do?

by silentsea90

3/28/2026 at 9:49:21 PM

I have a stoic mindset, I try to not care about things that are outside my sphere of influence. While the cancer was unfortunate it was out of my control. Having my YCW15 batchmate step up for me during my initial set of treatments to get me Shasqi opened my eyes that I could help create and take new medicines. It was within my sphere of influence. When I reached the end of standard of care I stepped down from the CEO role of GitLab and pushed to do this for me. While it was hard it was easier than I expected and I created companies to help other patients in the same way (maximum diagnostics and single patient IND pathway).

by sytse

3/28/2026 at 11:14:16 PM

Philosphical treatments have got a bad rap because it is so easy for conmen to convert them into fake hope, but when properly applied they are still amazingly effective. It's just that "properly applied" is very often not profitable because all the applicable texts and practices have been quite literally known for thousands of years and are available through well known texts in the public domain.

And Sytse if you read this: beterschap en als dat niet helpt: sterkte. Cancer sucks.

Sorry if this is too specific/personal, but I've been wondering, why does the treatment timeline include antibiotics (dalbavancin)? Does dalbavancin have any suspected antitumor effects, or was it simply to treat complications of surgery / catheter infections?

(edit: actually now that I checked the treatment timeline again it seems to be gone now. It was there 2 weeks ago!)

by meew0

3/29/2026 at 2:30:27 PM

Chiming in from Sid’s care team, the Dalbavancin was used to treat an infection post surgery, thanks for asking!

Thank you for sharing—very inspiring. I'm interested in the operations of starting and managing these companies in parallel. How did you go about finding people to run the companies? How much involvement do you have in their day-to-day operations? Are they "your" companies, or do you consider yourself just Customer #1?

by JakeSc

3/28/2026 at 10:06:17 PM

This is very impressive, top labs doing research often don't have experimental designs that are this elaborate. Was the TCR and BCR-seq you conducted helpful to design cell therapies, neoantigen vaccines, and monitor progress?

Given that you carry the HLA-B*27:05 allele, you might have been blessed by being predisposed to a better response. But probably you want to keep an eye on future autoimmunity issues. Talking from experience...

by nextos

3/28/2026 at 10:21:03 PM

Thanks for the warning, I hope that it wasn't a personal experience for you.

Thanks for the compliment about the elaborate design. I think that when you make something for one or a few patients it is easier to be more elaborate, even with the same knowledge and equipment.

Maybe the TCR and BCR-seq was most helpful for mRNA design and effectiveness monitoring, but hopefully someone else on my team will answer that better.

by sytse

3/28/2026 at 10:29:47 PM

The TCR sequencing has been helpful for downselecting TCRs for a TCR based cell therapy, and for monitoring response to various immune therapies (including the vaccines)

by jacobjstern

Having lost several members of our family to cancer over the last several decades, including my mother, I sometimes question where all the money going into cancer research has gone. Maybe what has been lacking are motivated patients with both the means and the intellectual capacity to drive for solutions. Again, I hope you find a path.

> Fasting (1 to n weeks) is said to provide potential benefits for certain types of cancer treatments. Pre-cancer, it is said to potentially prevent cancer onset. This is potentially powerful for those of us with a family history with cancer.

It makes sense. Cells need nutrients for the cell cycle, similar to the way computers need RAM to execute programs.

Fasting not only deprives cancer cells of nutrients, but also triggers a homeostatic response in the entire body. This response includes putting its garbage collection system (autophagy) into overdrive mode so that it can reclaim the limited resources it has left to survive. Fasting is a reductive treatment, like purging oxygen from a server room on fire. It might help slow it down, but it can take healthy inhabitants along with it.

Additive treatments offer more options. If you catch the fire early and it’s contained (non-metastatic), you can target it with a fire blanket (surgery, stem cell transplantation) or a fire extinguisher (small molecules, biologics, peptides, gene therapy, etc.) to put it out. The sprinklers are a last ditch effort for larger fires (chemotherapy, radiation), which could save the building, but result in significant collateral damage.

by RS-232

3/30/2026 at 4:36:24 PM

If we were serious as a society about fighting this disease we would engineer an approach that guarantees early detection on as many people as possible. My guess, not having looked at numbers at all, is that the societal cost of late detection must be staggering. In other words, I am thinking --and I could be wrong-- that even if we provided annual checkups for free with a suitable technology, it might be cheaper than the devastation caused by cancer.

While not all cancers are the same, we cannot ignore the fact that there's a metabolic link to cancer onset and development. Our industrialized food system simply isn't healthy. I don't know how we do it, but there has to be a way to alter behavioral patterns (nutrition, exercise, visceral fat control, substance abuse, etc.) to actually protect people from both bad inputs and, frankly, themselves.

I don't say "themselves" in the sense of suggesting an overlord scenario. The reality is that most people are ill-informed and our industrialized food system is designed to be supremely addictive. Anyone who has battled with processed food understands just how difficult it can be not to consume it, both from a widespread availability perspective and what it does to your brain.

Despite the fact that treatment options and efficacy have improved, without fixing these factors it will be impossible to win this battle at scale.

I think you’d find Dr. Richard Scolyer’s story really relatable. He’s an Australian cancer expert who, along with his colleague, is using himself as "patient zero" for a world-first treatment for his own brain cancer. They’re basically doing the research and the treatment in parallel to find a new way forward: https://www.abc.net.au/news/2025-10-30/dr-richard-scolyer-sp...

by plasma

3/29/2026 at 2:32:59 AM

I found his story to give my mom hope when her cancer had metastasized to her brain in 2025.

Cancer cells in the brain are in a nutrition rich environment for growth and at the same time dangerous for treatment for removal and to prevent growth. The expected 5 year life expectancy is less than 5%.

Dr. Richard Scolyer had been diagnosed at 2023 and is still with us today. I hope he succeeds in his work.

by binsquare

3/29/2026 at 7:00:42 AM

This is fantastic and I would do something similar if I had the same resources.

Whole genome sequencing and single cell sequencing are actually surprisingly inexpensive (compared to the cost of almost any cancer treatment) and there is a good argument that we should do this by default for any type of cancer for which there are not effective treatments.

I would encourage all patients to learn as much as possible about their own diagnosis. There may be clinical trials available in another centre that your clinician is not aware of or tumour-agnostic trials that target specific mutations that are present in a range of different cancers.

There is a good argument for allowing patients to try experimental treatments once standard treatments are exhausted. The provider liability issues could easily be solved by legislation. A bigger issue is that there will always be people who want to exploit vulnerable cancer patients by charging exorbitant amounts for plausible-sounding treatments which have no evidence base.

As an individual trying multiple experimental treatments at once is the logical approach if there is no other option. However it will not be possible to know which of these is effective and which have caused side effects so to develop more effective treatments we do need structured and carefully controlled clinical trials. Unfortunately there is a huge regulatory burden for any kind of clinical trial at present and this should be massively streamlined for cancer patients where even if the treatments cause harm the alternative is death.

This is the most supremely motivating post I've seen in a long time. I know what it is to be diagnosed with cancer, being rushed to surgery - it's amazing how quickly the medical-industrial complex can move once you've got a diagnosis (at least in Australia). I had a short period of contemplating terminally, because cancer claimed the life of most of my family. Thankfully, after surgery it was gone.

To see Sid use his motivation and resources to solve his own problem is the core message (IMHO) of the hacker community.

It makes me look at my own problem (Peyronies) in a different light; a disease which has affected my life in ways which cannot be overstated. Yet, all the money in the world right now can't fix Peyronies - yet in reading his journey my mind has been changed about this.

His slide title: "I'll talk to anyone, I'll go anywhere, and I can be there anytime" is certainly the mindset!

Thanks for posting this - I'm inspired to take similar action for Peyronie's. Anything is possible.

I commend you for speaking openly about Peyronie's, I imagine that isn't always an easy thing to do (or to deal with). Best of luck, and I hope you manage to make progress with it. Effective treatment wouldn't get as much airtime as effectice cancer treatments, but it would certainly have a positive effect on the lives of millions of men.

by elric

3/28/2026 at 8:50:28 PM

You are right on the mark. What triggered me was the slide in Sid's presentation: "Assessing Fibroblast Content of Tumor". Peyronie's is all about Fibroblasts. I actually typed my reply quite a few times, deleting mention of Peyronies and retyping it. It's a shameful condition for me, and I realize that I have to get over this. Peyronie's affects 1% to 20% of men, primarily because it's (if you're anything like me) - is impossible to talk about.

Again, you're completely right. Talking about the disease is the first step.

It’s not quite the same, but I had a frenulectomy done due to severe phimosis leading to pain and bleeding. It was absolutely horrible, and I was shocked at how hush hush we all treat conditions like this.

Thankfully there’s a straightforward surgical treatment for it, and I hope that you’re successful on your quest around Peyronie’s!

by girvo

3/28/2026 at 10:44:42 PM

This reminded me of my own story, when I was 15 and had phimosis. I was embarrassed to talk about it with anyone, so in my desperation I posted about it on a forum that claimed to help kids in need of help. Someone responded and gave me instructions that they claimed had a high success rate at treating the condition.

I followed the instructions for a few months and it fixed it. I went back and sent the biggest thanks to the responder. I did not expect to get any help from a random forum.

There has to be swathes of kids struggling with "embarrassing" (in quotes, because they actually aren't embarrassing at all) issues like this. I hope today's internet can provide help to the ones that have nobody to discuss them with.

I am watching DTF St. Louis (which is not a terrible reality show about a third tier city like the title implies, actually a Jason Bateman kind of dark comedy/whodunit), and Peyronie's features in the story. The show also has the first commercials I've ever seen for a Peyronie's treatment, and apparently it's an official ad partner of the show. I wonder if some enterprising show exec decided to go pitch the perfect sponsorship or if the company making a treatment commissioned a show...

Given your personal experience, I expect you know significantly more than I do, but I just wanted to note: about 20 years ago, I was part of a small company that filmed and edited educational, medical videos for various clients. One of the main things we filmed for a while were Peyronies repair surgeries. They were using a product called Surgisis from Cook Medical as a tissue scaffold to straighten things out. It looks like, sometime in the past 20 years, Cook may have moved on to a new product called Biodesign: https://www.cookmedical.com/surgery/the-path-from-surgisis-t..., but I don't know anything about that.

You may know all of this already, and it may not be relevant to your situation at all, but in the slim hope that my experience of editing scores of Peyronies surgery videos may help nudge you in a new or helpful direction: there you have it!

by cade

3/28/2026 at 11:46:09 PM

Thanks for your thoughtful comment! You're right - Biodesign can be used in Plaque Incision and Grafting (PIG) for Peyronies. Unfortunately PIG IMHO has (in some studies I have read) a 50/50 chance of erectile dysfunction, nerve injury, instability and so on. In essence, PIG might be rolling the dice to make a bad situation completely untenable. But again, I do thank you for your comment!

Several years ago I was doing advertising websites, one of our customers was (Pfizer? Bayer? both were customers) they had developed a drug against Dupuytren's contracture[1] and apparently found it effective enough against Peyronie's that we were asked to create a website describing this (possibly off label) use of that drug.

Honestly I have no idea if it was effective or not, nor do I know anything about the side effects, but just in case you were unaware of that particular option I want to put it out there.

From what I can find, doing an online search along that path it might have been Xiaflex/Xiapex by Pfizer.

(Not paid by anyone in this particular business anymore, just remembered it when I read your comment).

by MindTwister

3/28/2026 at 8:46:04 PM

Thanks for your comment. I'm aware of Xiaflex, and it's been clinically proven to work against early-stage Peyronies. When the disease has reached the chronic phase (and calcified) - Xiaflex hasn't been clinically proven. Xiaflex is now on-label for treating Peyronies.

My mistake wasn't acting earlier, because I had no idea what was happening. But thank you again for your comment. Thank you!

In the NL the only option was Tunica albuginea plication (TAP) which results in a loss of length. I've read that PIG in 44% of cases fixes this, however... ugh... surgery.

by fumeux_fume

This is a common trope in the tech field- successful tech person who is good at tech gets disease and wants to help cure it. It's easy to generate a lot of data these days (whole genome sequencing, various tests) but the reality is that turning that data into actionable knowledge is remarkably difficult.

Much of the red tape exists to help people avoid making common mistakes that aren't obvious until you've been through the process a number of times (other red tape just exists to gatekeep unnecessarily).

by dekhn

To be somewhat more optimistic, digging useful connections and correlations from a heap of data is something that AI is really good at.

IIRC there is a cancer lab in Vienna, Austria, where they feed genome sequence of a tumor into an AI and it sometimes recommends unexpected-but-efficient treatments.

by inglor_cz

3/28/2026 at 8:27:27 PM

It's wild to me to hear this being spun as vanity, like it's some influencer clickbait or linkedin slop. You could argue anyone posting anything online is driven by vanity, but in this case we're talking about someone who took agency in his own medical outcome, and essentially experimented on himself. Sure it was selfish in the sense that he didn't want to die and he bent all his effort and resources to it, so what? I don't see exercising ones will-to-live in this way being a huge moral gray area. Other commenters are saying why don't we fund more research? Well sure we should do that too, but it's important to recognize that the type of approach he took here only works because it was one individual willing to combine a significant amount of personal effort with his own moral authority to try out risky things on himself. Even with orders of magnitude more funding, you can't ethically do this kind of thing without the consent of the patients, and there's not enough data on these types of approaches to adequately describe the risks to patients if they aren't specifically motivated to lean into the details like this guy did.

A very motivating post. What he said “It became my own job to keep myself alive. Nobody else was going to do it for me at this point” really stayed with me. It’s powerful to see someone take that level of responsibility in such a difficult situation. I also appreciate how his ability to fund his own treatment can end up benefiting the broader community.

While that is just a natural reaction to "unfair" world where not everyone gets the same level of access to the best level of care, I'd also say that it's a reminder that money can't and won't solve all problems people are hit with in their lifetimes (or he'd not be facing cancer diagnosis in the first place).

This story is of someone with resources putting them to good use to save themselves, but also have that benefit others: medical research is expensive and for good reason restricted, and just like lots of open source was driven by individual's need, so lots of good stuff can come out of this. I suggest to see it that way.

Maybe it's time for him to give the metabolic cancer theory a go and try to bump up his mitochondrial function as much as possible? It's practically untestable due to science testing all compounds in isolation instead of a cocktail over longer period of time that can't be properly controlled even if it might be true. Every single cancer cell has a damaged mitochondria and often switching it properly on leads to cancer cell's apoptosis. He should also take desloratadine as some Swedish hospital observational study showed a significantly increased survivability on all tumor types with it. Some people had success with the combination of DCA, R-ALA, B1 HCl megadoses >2g, CoQ10 + PQQ, glucosidic astaxanthin, nattokinase/serrapeptase/lumbrokinase, low-dose aspirin, pancreatic enzymes and lactoferrin, with complete removal of fructose from the diet (as the cancer explosion can be correlated with years when fructose started getting introduced into diet in large quantities).

You get ill and well multiple times before you or it wins. And the known therapy modalities remain the same since 2500 years (surgery, toxin, burn). Genetics failed loudly in this field. It's all statistics, prevention and luck. Hope all well to the guy.

Kudos to Sid for trying it and hopefully it benefits others in the long run. Not everyone has the money, will or commitment to do this. My own father died with a battle of myeloma, a blood and bone marrow cancer, after 2 years, it wasn't the disease specifically that got him, it was the secondary conditions that caused irregular heart rhythm and eventually one day it stopped and no one was there to help. 2 stem cell transplants, rounds of chemo, almost full failure of kidneys. The cancer did its job. Ultimately what I'm saying, the medicine gives us time, but no one beats death. Maybe the treatment gives us time to come to terms with that, hopefully my dad did. I was in total denial. Anyway good luck to you Sid.

All the best to all the cancer survivors out there, and to the loved ones who lost them.

When it comes to cancer, there is an awful lot of legacy thinking and "way things are done" taking lives. Starting with the so called "standard of care", which makes patient lose precious treatment windows while they wait for a possible miracle from "first-line drugs" from thirty and forty years ago which frankly are not that good. But it's hard to reform because the fraction of people who ever think about cancer as a problem to be solved is quite small; and it ought to be far larger, given that cancer is the second or even first leading cause of death across much of the world. I wish Elliot Hershberg every success.

by dsign

3/28/2026 at 6:35:02 PM

I'm pretty much a pessimest when it comes to fighting cancer. I think it's just one of the bugs in our genetic code that evolution didn't shake out. I say that not as a biologist or anyone who has done any work in the field. But I've seen people close to me die of cancer and it seems like the treatement is almost worse than the disease. I agree that the standard first attacks are very crude and have broad systemic side effects and the attitude seems to be "you'll die without this so that doesn't matter."

I read some stuff about mRNA treatment a while ago that seemed like it might be promising.

by SoftTalker

3/28/2026 at 7:10:22 PM

> seems like the treatement is almost worse than the disease.

I think that's what the poster above you was saying. "Oldschool" chemo is basically poison, and the hope is that it kills off the cancer before the patient. But there are newer drugs that are extremely effective with way way way less side effects out there, depending on which type of cancer one has. Things like immunotherapy are really effective if you happen to match their targeted types of cancer, and some have basically 0 side effects, leading to a QoL improvement if they happen to work. People have gotten nobel prizes for some of these discoveries, it's really insane how far we've come in the last 30-40 years.

by pavas

I work in this field. It’s more or less correct but kind of lacking in detail. Cancer is a property of all multicellular life. I think it’s best understood as the behavior of a dynamical system that loses the feedback control that keeps cell growth under control.

Check out this paper from the Lander lab: https://elifesciences.org/articles/61026

It’s a bit jargon heavy but it’s a nice case study in how tumor growth is controlled through all the same mechanisms that normal tissue growth uses. Even cells with an outright cancerous gene mutation are basically still just doing normal growth and development.

by bglazer

3/29/2026 at 9:18:30 AM

" Cancer is a property of all multicellular life."

In practice, though, some species are way less prone to cancer than others. Orders of magnitude of a difference, even in mammals. Bats, notoriously. Or naked mole rats. On the other hand, mice get cancer fairly reliably.

Which means that there are biologically realistic way how to keep the danger at bay, and they seem to involve the immune system.

by inglor_cz

3/28/2026 at 9:01:39 PM

I am guessing: There is an evolutionary "shadow". Genes for getting old and healthy are not selected for, because you get old after having children. Evolution optimizes for the survival of your children.

Might be that cancer hits after creating offspring.

by bashkiddie

3/29/2026 at 5:10:15 AM

In a social species such as ours, with such a prolonged childhood, having healthy parents and grandparents is likely to affect the survival of children so there will be some selection pressure on a long life there.

Cancer is too broad of a term. Some cancers like Hodgkin's lymphoma or testicular cancer respond extremely well to treatment. Some cancers are caused by cell damage from viruses such as HPV and can be prevented by vaccines.

I get the pessimism because "curing cancer" can essentially be interpreted as "curing aging" but progress is being made.

Sounds like some lame ass tech founder bullshit if I’ll be honest.

If I had cancer the last think I’d be thinking would be to make a slide deck about it.

Can these robot people come back down to earth and have a genuine human experience for a chance? Not everything has to be framed in the view of a startup company or a data analysis exercise.

Maybe focus on spending time with your family and friends? If they still like you after years of being an insufferable tech bro.

He’s been public that he’s ten months clear now. Some prefer to accept undesirable circumstances. Others prefer to oppose them. He’s one of the latter. A little paraphrase of Dylan Thomas’ work here is something I’m fond of:

Do not go gentle into that good night

Rage, rage against the dying of the light

And if he’s successful, which hopefully now he has a much better chance of, there are all these new medical results out that are useful.

As an example, a close friend is using one of the personalized medicine companies that sytse’s “CEO of care” has invested in to diagnose a persistent debilitating condition with no specific cause.

Or to quote someone else: All progress depends on the unreasonable man.

by dominotw

3/28/2026 at 11:40:30 PM

Before I got my Prenuvo MRI everything online said “don’t do this, man. You’ll find all sorts of things that will worry you that you wouldn’t be worried about if you didn’t do it”. That makes no sense to me. Totally irrational. So I did the scan and saw a bunch of things which had no clinical significance - including the amusing thing that I’m missing the transverse processes on a couple of vertebrae (easily explainable from a motorcycle accident that put me in the ICU). So I moved on, scan done, and with the docs in my family reviewing.

But a friend of mine went through a different diagnostic procedure and found things of equal clinical significance and went through a large number of interventions which he didn’t really need it now turns out. And then I understood why people provide this warning.

So the first question to ask yourself is which kind of person you are.

by arjie

3/29/2026 at 5:50:57 PM

There is a chicken and egg problem with advanced diagnostics like Prenuvo. I’m optimistic that if all disease were to be caught early, (1) the health system would evolve what is standard of care downstream in the working up and treatment of findings and (2) as individuals we would be less likely to overreact in chasing stuff down and feeling anxious. As CEO of Prenuvo, we do our best to contextualize and risk stratify in what is an evolving practice.

by andrewlacy

3/28/2026 at 6:43:15 PM

Not really. Osteosarcoma rates have remained very stable for decades. Some young people are getting diagnosed with colon/breast cancer at increasing rates, but most of that comes down to better diagnostics and imagining, catching things at earlier ages.

by TaupeRanger

But isn‘t colon cancer in young people primarily an example of rates actually increasing, because young people specifically often get easily dismissed based on their age.

"maximum diagnostics"

Love this! This is the way! And he proved it correct.

I remember one time I mentioned this in a casual conversation only to get back very low IQ responses with some fatuous arguments that the tests caused the disease or something.

There was this one guy Tomas something (can't remember the last name, a weird one), doesn't matter, what I do remember is how he was desperately trying to explain how more tests led to more diagnoses and that was ... somehow bad? Lmao.

Something I've observed, I've lived in Canada/US and Latin America, in the former you have to wait months for a CT scan, in the latter you can get it the same day you need it. If the "third-world" can do it, there's no excuse.

He is lucky to have the resources and determination to start his own companies and tackle the problem himself. I wish the majority of tech bros would act in a similar fashion.

The sad truth is, that in most countries, health systems do not allocate sufficient resources or financial support to doctors to correctly diagnose medical conditions accurately as it is not in their economic, interest to do so.

Quick, without doing any kind of Googling or calculation: if I asked you to count 3B grains of rice by hand, how long would that take you? How big would that pile of rice be? How long would it take you to eat it?

A billion is already unfathomably large. If you think it isn't, you just haven't tried imagining what a billion of anything would be like.

by crote

3/28/2026 at 11:58:13 PM

The problem with this exercise is that I have a few million in wealth and I cannot actually visualize a few million grains of rice but I am fully aware of my total capacity to allocate capital to problems.

Neither $3b nor $300b are realistically unfathomable to me. I find them easy to consider in terms of the projects I can build if I achieved each of these amounts.

As an example I’d have to allocate somewhere between $50m to $250m to get people to vote on a California proposition. I’d need to spend $1.5b to create a wing of a major hospital. I’d need between $100m and half a billion to create a new K-12 school in my city.

These are large sums of money and are currently out of my reach so if AI doesn’t destabilize everything my best bet is to take the same approach each of my ancestors did. Move my children one level up the wealth ladder and hopefully give them the values that help them prioritize these actions and the optimal way of getting there. I think that involves some amount of compounding and then some amount of spending.

Yes, big number better, everyone gets it.

The point is that you’re deluding yourself if you think that there is any difference in terms of relative “unfathomability” between 3 billion and 300 billion.

3 billion generates more in interest per day than 99.99% of people make in a year. That’s unfathomable volumes of wealth for even the very rich.

by CommenterPerson

3/28/2026 at 7:01:47 PM

(slightly sarcastic) So we should give rich people diseases so they are incentivized to fund medical research?

Sid seems like a decent person. I'm glad that he's able to push cancer research forward on his own. Hopefully his work will make things better for everyone else with bone cancer. Seems like that is well under way. (and I guess I should recognize that he funded a cancer treatment company years before he knew he had cancer further reinforcing that he's not purely self-interested)

I'm a little melancholy that my aunt, who was a millionaire just not a mega-millionaire, didn't have the resources to do this before she died of cancer. She was able to pay for a high standard of care, but couldn't single-handedly fund teams of scientists to work on her case. I know she would have done so if she could, her biggest regret was not being around longer to see her grandkids grow up and she was very driven to watch over her family.

It is a little sad that the world's medical research apparatuses couldn't seem to fund this on their own. Not just the US medical system, but Europe and China also don't have better treatments until a rich guy came along. It seems that it's not for a lack of ideas, just that some of these ideas couldn't be funded. Is it that this type of bone cancer is super rare and the cost just isn't worth it? Or are we just under-funding at the level that several ideas with a likely positive ROI aren't able to get funded?

by parsimo2010

3/28/2026 at 7:09:27 PM

Why can’t we just ask our governments to spend more on research? Want some rich person to donate $100 billion on cancer research?

by melling

3/29/2026 at 9:22:28 AM

It is a bit simplistic to assume that more money translates into better research outcomes.

Alzheimer's is a warning tale. Lots of money flowed into research of this condition, and was mostly wasted on a flawed hypothesis supported by scientific VIPs who had a face to lose in case it proved incorrect.

We don't necessarily need more money in research, but smarter ways of spending it. The current grant system rewards established players and reliable production of mediocre (or even fraudulent) papers over honest failure and actual innovation too much.

by inglor_cz

by declan_roberts

3/28/2026 at 8:59:13 PM

It's a problem of incentives.

Governments have a limited (although large) budget, and no incentive to spend it well[1]. You don't get promoted as a government administrator if you approve a Nobel-prize-winning grannt.

If you don't get rewarded for good work but may get punished for taking risks, you optimize for risk minimization, even if this means a lot of potentially-good work not getting done.

Nobody blames the FDA when millions of people die from the-medicine-hasn't-been-invented-yet-itis, everybody blames the FDA when ten or so people die from a side effect nobody saw. This impacts FDA policy.

This person has the best incentive there is in the world, the incentive to live. He didn't care whether the people getting his money correctly filled form 437-F, or whether they have the relevant paperwork that verifies their legitimacy in a way which can be described by legal rules.

[1] Incidentally, finance has (had?) the opposite problem. If your bonus is calculated as min(0, percentage * profit_generated), you will maximize risk, optimizing for bets that give you great returns most of the time, but wipe you out completely some of the time, as your losses are clamped to 0.

by kelnos

No we absolutely don't. The US hardly spends anything on research.

The entire yearly budget for the National Cancer Institute is $7 billion dollars. To put this in perspective, that's 3 days of funding the DoD. For cancer. That kills well over half a million Americans per year.

The takeaway is that we should invest in research rather than letting people die.

Cancer research, and all research in general, is massively underfunded. The US spends $7 billion dollars per year on the National Cancer Institute. The EU spends about as much as well. That's $14 billion per year for all cancer, never mind bone cancer. This just isn't a lot of money. That's like 6 days of running the US DoD. For cancer.

In individualistic societies, the cultural motivation isn't going to come in the name of collective action. In the era of how much state funding of state driven science in the US is being pulled, you're 100% correct that all that will be funded will be rich people looking to cure themselves. But just because it's factually correct, doesn't mean it's not an indictment of the society we've built.

mRNA research, first discovered in the 1960s, couldn't get much funding for years/decades and had to scrimp through what they had. And then it got a burst in funding and was publicly available in a year.

There are so many diseases that can be solved if money isn’t an issue. The problem is even if this wealthy guy cures his own cancer the treatment will never be available to us. We still do not have cheap genetic targeting and immunotherapy. The average person will be bankrupt just from the discovery.

I’m of the opinion most types of cancer can be targeted and cured. There’s just not enough money in it to produce the cure. The entire industry is locked behind a paywall.
