    The first point is by far the most important. The US healthcare system (and probably others) is an unfeeling machine and you have to treat it that way. Ask for earlier appointments, cancellations, and referrals to other specialists. Navigate it as if nobody knows (or cares) what you're up to. Doctors tend to only exist within their silo and it's often on you to request a different type of doctor or even another one of the same type. Be a pain in the ass, your survival may depend on it.

    Personal story: I was having trouble using my left arm. Like, couldn't lift or type or do much of anything with it. Was told it was a pinched nerve by physiatrists and orthopedists, despite having no pain. Only when I specifically requested for a referral to a second neurologist did he order the head MRI which exposed a brain tumor in my motor cortex. We were able to move quickly and get me on a treatment plan which has bought me a lot of time. Had I not advocated for myself, it would have probably mutated into a much worse type and killed me soon.

      I had to quite literally sit in a doctor's office and make a public nuisance of myself to get a referral for a family member to a specialist for cancer when the regular doctor said it was just back pain. Then I drove the 2 hours to their office to get the appointment. It was lymphoma.

      People can't ignore you as effectively if you're in their physical space. When it comes to your health or the health of your family, do not back down. Doctors are used to nuts who googled the symptoms or joined a Facebook group and have all the answers already. Make it clear you have NO answers but NEED them asap.

      • helterskelter2 20 minutes ago
        I've had similar experiences. It's kind of terrifying, actually, you have to walk the line of being annoying enough to get what you want but not so annoying they completely ignore you.

        One of the things I've learned is to apply the Socratic method, preferably in front of their colleagues if they try to brush you off. Also, if you've got scary symptoms, demand they write down what your symptoms are on your record and why they aren't concerned, then demand a copy of all relevant records (it's your property) -- this often gets them to reevaluate your risk in terms of their career.

        Worst case scenario, you can make up medical history. I had a family member pass recently from colorectal cancer. They had symptoms but their PCP kept insisting they were too young. My family member suddenly "remembered" her aunt died of CRC when she was a kid. This got her referred to a gastroenterologist, and they found out she was stage 4...after her PCP delayed her diagnosis for like a year. She actually had grounds for a malpractice suit but who's got the energy or money for that when they're fighting stage 4 cancer?

        Also, know your state's agency responsible for policing health insurance. This family member's insurance company routinely tried to deny life saving procedures, but a call to the right govt agency set them in line each time.

        This is something I don't understand of the US and other "developed" countries health systems.

        Here in Mexico, i can get to doctoralia and make an appointment with a high specialist , like a Vascular Neurosurgeon. All by myself. The first visit will to maybe $200 usd (and that's very high) and normally it's a week away at most. No waiting on the private health option.

        Of course if you go with public health, it's a disaster and a shame.

      I have a similar but more benign story, and cannot emphasize enough how correct this comment is. I had severe abdominal pain and vomiting. My PCP told me it was GERD and I should lose weight. Two days later I was getting an emergency cholecystectomy because my gall bladder had necrotized.

      A good shorthand is that unless a doctor has positively identified something through imaging or biopsy do not trust them when they tell you what something is or what to do about it.

      If you aren't sure how best to advocate for yourself, use AI to help figure out what tests and referrals to ask for. You might feel like a jerk, but don't expect anyone to care about you more than you do.

    • kokon 12 minutes ago
      Been gone through something similar. It's important to be persistent. My PET-CT was originally scheduled for 6 weeks, and they couldn't get it sooner. I had to call every imaging labs within 50-100 miles radius, eventually got one within the next couple of days.

      The next important one is to find the best doctor you could afford. I didn't have a lot of faith on my local oncologist, especially when he said that my cancer (nasopharyngeal carcinoma) is rare and had not much experience with it. I was able to get ahold of the chief surgeon at UCSF, purely by luck. Felt a lot better when he said that this type of cancer is pretty common for south-asian descent. He has dealt with it quite often due to a large concentration of asian in the bay area.

      The treatment sucks, but small price to pay considering I can spend more time with my family.

      The number one thing I tell anyone who is going through any sort of medical situation that requires extensive care, you have to be the biggest advocate for your care. If youre not comfortable doing that, then find a loved one who will stand by your side and be that person. Healthcare is a business and you need to treat it with the same vigor you tackle business problems because your issue is a business problem to them.

      Don’t forget, Doctors are just well read mechanics

      Oh my. I did not expect this.

      I'm glad you caught it early, and I hope you have the best outcome you can, and thank you for sharing your story.

        If you've dealt with the American medical system then stories like this aren't very surprising. I'm not going to act like this is everyone's story (a lot of people have pretty smooth experiences) but it happens a lot more often than it should.
        • SoftTalker 26 minutes ago
          It's not unique to America. Specialists are in high demand everywhere and seeing them means you have to pass through a screen of generalists who first rule out all the common explanations for your symptoms.

          But GP's point is otherwise true. It's just a job to them. They see dozens of sick people every day. There's no way to be empathetically engaged with all of them or really any of them and still be effective. It's not personal, and they aren't ignoring you. You're a bug report in their ticket system. Understand that and you'll be able to deal with the system more effectively.

          • sippingabonedry 12 minutes ago
            If you have halfway decent insurance in the US you do not need a referral to see a specialist.

            The exception to this rule is if you are in an HMO like Kaiser which force you through "level one support" (your GP) or if the specialist is so busy they require a referral to screen out the social media schizos.

    • elmer2 36 minutes ago
      It's worse everywhere else. There are no specialists in all of the government-run systems I've dealt with and at some point, you really have no options left.

      Canada introduced MAID for this reason.

        > There are no specialists in all of the government-run systems

        This is completely inaccurate. Every government run system has specialists.

        Everything you have said is incorrect.

        • computerdork 24 minutes ago
          It's an over generalization but think this person has a point. The US health system has it problems (cost!!), but have read that since it's money driven instead of a government service, compared to other healthcare systems, it's often got a shorter wait time to see a doctor. This makes sense, a lot of students want to become doctors in the US, because they can make a lot of money
          • louthy 3 minutes ago
            > but have read

            You read that where? What evidence do you have? In my experience, Americans are often blissfully unaware about how poor their health services are.

            As someone who has seen many health services up close (from selling health software and literally visiting myriad health establishments around the world, over past few decades), the US system always strikes me as the most run down.

            And whilst the US does ok with cancer outcomes, so do other nations like Germany, Switzerland, Japan, South Korea, Singapore, Canada, and the United Kingdom.

            Most advanced nations have universal healthcare with similar outcomes to the US but for significantly less money.

            The US system funnels profits, it doesn’t provide better healthcare.

          • InexSquirrel 12 minutes ago
            I feel like the >(cost!!) factor can't really be overstated there. IF you have money then you can get healthcare, if you don't, then you're out of luck. It's a massive gate which needs to be passed, and if you can't pass, then you're locked out with no alternative.

            That doesn't sound great to me (read: broken), because it means its not evenly accessible across your society. I wouldn't count that as a good system to be honest.

            I have limited experience with the New Zealand and Japanese medical systems, and from a similarly arms-length engagement with them, I think I would prefer them over everything I've read about the US system. You still have the same issues with having to advocate for yourself, but you can at least get access to good healthcare across the board - and if you go private (which as a late 30s / early 40s guy, cost around NZ$60 / month), you can get access to care at private facilities much faster than via public.

            It is most definitely imperfect, but it _is_ designed to be accessible to everyone.

          • snapetom 1 minute ago
            I explored specializing in health econ in college. My professor put it this way - health care is a scarce good. There's only so many doctors, so much medicine, so many beds. You have to control access to the goods somehow, otherwise you have Tragedy of the Commons.

            In the rest of the world, it's controlled by extended wait times. In the US, it's cost. You can have moral arguments about what's fair, but that's the economic reality.

            At the time I as studying this (early 2010's), the average wait time of diagnosis to first treatment for breast cancer in the US was 12 days. In NIH, it was 5 months.

    • mmoustafa 38 minutes ago
      I had a heart condition (myocarditis) recently after a viral episode, despite the obvious prognosis the ER doctor treated me for a heart attack instead without consulting a cardiologist which sent me to the ICU.

      I should have mistrusted the doctor and trusted the AIs more, unless they gave me compelling reasoning. Don’t give up your decisions to anyone, incompetence is abound.

  • stochastician 41 minutes ago
    The second opinion advice is great, and what I tell everyone I know who gets cancer.

    My mom was diagnosed with stage 1 cancer in 2006 in Idaho. I was a PhD student at MIT at the time and a friend in lab helped me get an appointment at Dana-Farber. I thought it was probably overkill (it was a common cancer) but we did it anyway. They said everything in Idaho was standard of care but suggested one extra test, which Idaho team then reluctantly did, which revealed distant metastasis (stage 4! ), dramatically changing her treatment trajectory. She lived another 15 years (I miss you Mom).

    Asking for a second opinion sucks. A lot of us are preconditioned from birth to trust our clinicians. But you're going on a journey and your life (or the life of your loved one) is on the line. Insurance often covers it. Your doctor will NOT be offended.

    Think of it this way : if you were deploying code to the mars rover, and your colleague asked to do a code review before you pushed go, would you be offended? This is even more important than that.

    • mrmincent 24 minutes ago
      Yeah absolutely on the 2nd opinion, my dad went into his GP and said “I think I have lung cancer”, after a period of difficulty breathing and low energy. The GP diagnosed him with low iron and gave him some iron supplements, didn’t even get a scan. A few months later he had to have a couple of litres of fluid drained from his lungs while on holiday, turned out to be mesothelioma. Obviously we’d prefer it to be low iron, but better to know what is going on and be able to respond to it.
  • exhilaration 45 minutes ago
    My suggestion is that if you're within a 2-3 hour drive of major cancer centers - just use the US News list https://health.usnews.com/best-hospitals/rankings/cancer - go there instead of your local community hospital. The top cancer hospitals in the world accept your health insurance (probably), so why not go there? Use your vacations days, book hotels if you have to - this is the time to go all out.

    My experience: I was horribly sick for 10 months, none of my local doctors could figure it out, then I drove to Penn Medicine in Philadelphia and they did the right labwork in the first visit. These top centers just have different mindset than your community hospitals.

  • runjake 58 minutes ago
    This is fantastic. Thanks for posting it, JJ. There's a very strong chance you'll save n>0 lives by posting this.

    Minor addition: When you talk to someone who has undergone the surgery, try to find someone that's a similar age and in similar shape to you, otherwise you may get wildly varying answers.

    You'll respond, experience and heal from a surgery quite differently at 40 vs 50.

    As a fellow cancer-haver, I would give a piece of proactive advice for those (in the US) who do NOT have cancer or even suspect they have it:

    Find a decent primary care doc who is not impossible to schedule with. Someday, if you do have a problem, the primary care doc will be able to send you off for scans, etc. much more easily when you are an existing patient. Getting appointments as an existing patient is much easier.

    > AIs may downplay the seriousness of things. I was chatting with various models and most pushed me in the direction of “you don’t have cancer” for a while. Just something to note.

    This is certainly another data point for "never trust AI chatbots".

    • aantix 8 minutes ago
      Disagree. You don't take the evaluation at face value. You still push back and explore every thread. You don't abandon your own logical reasoning.

      But you definitely want to scour the entire search space for solutions.

      And the most efficient means for that is LLMs.

      It's my experience that doctors are compartmentalized in their thinking, limited in their time, and definitely will not be extensively exploring your case.

      E.g., I had 30 years of resistant hypertension. Multiple medications. Saw many cardiologists. Nephrologists. I was told to "just lose weight." BP was erratic over the years. ER visits. It was awful.

      I googled. Pheochromocytoma. Hyperaldosteronism. Asked the cardiologist, "Could it be this?"

      "NAAAAH, just lose weight."

      But I insisted on a referral to an endocrinologist. And when I suggested it to them, given my extensive history, they were basically like, "Oh yes, we'll get you tested. I'm surprised you haven't been tested before?"

      I had a left adrenalectomy 6 months later. BP has been controlled ever since.

      They don't know everything. They can't.

    • dekhn 50 minutes ago
      Statistically, it makes sense- most people asking AI if they have cancer don't have cancer, so a model that is lacking detailed information should basically be returning based on the basal rate of cancer in the population with a threshold applied.

        But OpenAI said we have AGI now...
        • dekhn 39 minutes ago
          I think it's a truism that naive computer science people who have watched the rise of computers, the internet, and AI will always believe that curing diseases is a straightforward process and that new tech will rapidly fix all the old problems.

          The folks who actually go work in the field, understand the structural problems, the costs/benefits, and the long slog to bring successful treatments to patients are skeptical. But we're still more than happy to be proved wrong- if Anthropic (more than OpenAI) is working on life sciences and drops some amazing information that transforms cancer care with massive positive results, we all win.

          • imoverclocked 21 minutes ago
            > we all win

            Do we all? Or does anyone with enough money to pay for Anthropic's IP, win? Nothing states that Anthropic/OpenAI/... have to share information they have generated. As the crunch for income becomes real, I doubt valuable things will remain free.

            • dekhn 18 minutes ago
              I don't see any scenario where showing that we can tremendously improve medical care, even if it's IP/trade secret from an AI company, isn't a win, when integrated over all the variables.

              If they succeeded, you can bet everybody else will be duplicating their results within 2-3 years.

        • matteoraso 13 minutes ago

        Should it? Or should it say it can't be sure and to ask a doctor?

          Gemini says what I think makes sense (there are multiple responses which could make sense)

          [ if I gave you a picture of something on my skin could you diagnose it as a melanoma ]

          No, I cannot diagnose skin conditions or identify melanoma from a photograph.

          AI-based image analysis cannot replace a professional medical evaluation. Skin conditions—especially potentially serious ones like melanoma—require a physical examination, and often a dermatoscope or biopsy, by a qualified healthcare professional such as a dermatologist.

        • qurren 25 minutes ago
          AIs often keep blabbering "ask a doctor" after every medical question and I absolutely despise this behavior.

          99% of the time I'm asking the AI medical advice questions because (1) there is no specialist available on short notice (2) most specialists I actually see do not give me the sense they take things seriously enough (3) a lot of specialists are just incompetent.

        • sublinear 42 minutes ago
          > Or should it say it can't be sure and to ask a doctor?

          It's an extremely slippery slope to having it say that about even the most basic medical information.

          If you don't believe me, try any google search related to something as simple as hangover tips. The AI summary will tell you to call SAMHSA and then brutally stonewall you on anything else even tangential to alcohol.

          • dekhn 32 minutes ago
            I can't reproduce your claim. I get a medically correct response from the AI summary and then a link to the Mayo clinic at the top of the search results.
    • snazz 46 minutes ago
      This is the opposite of the experience people have when googling symptoms, though, where you often find articles suggesting that you’ve got some very serious condition when you do not. Interesting that the human bias when reading WebMD type articles is the opposite of the bias of LLMs.
      • mnw21cam 23 minutes ago
        That's not universal. I work in genetics, and we did an investigation a few months back, by asking various AIs whether a particular mutation causes $DISEASE. Invariably they were very strongly biased towards saying yes, even for completely obviously benign variants. I think that's because the majority of the literature out there describing variants is describing pathogenic ones, because why would you write an article about a benign variant, so the only material it has ingested is articles describing variants as pathogenic. In reality, the average person has millions of variants, and almost all of them are completely benign, so there should be a very strong pre-supposition that a given variant is benign unless there is fairly strong evidence saying otherwise.
      • the_af 18 minutes ago
        True! However, don't both biases point to "don't (primarily) decide by googling or asking an LLM"? You'll either be extremely scared or extremely reassured.
  • amoorthy 12 minutes ago
    Solid advice. On the point about surgery, seems obvious but surgeons are inclined to operate. They aren't inclined to tell you the surgery is unnecessary. They always say it's routine and they've done it many times before. All true but surgery can be very tough on your body as I saw with my late father. Complications happen more than anyone will admit.
  • sehugg 49 minutes ago
    This goes for any medical expense, but also beware of the "Coordination of Benefits (COB) Questionnaire" required by your insurance company. They want to confirm your other coverage (e.g. Medicare) once a year, and sometimes the only way you know they are expecting it is when you get a call from your doctor's office that your claims are being silently denied. The insurance company won't send you an email, a call, or a ding in the portal, the language is buried at the bottom of a page of one of those PDFs you have to explicitly download.

    I've had luck with just calling once a week or sending nastygrams asking why my claims are still denied, they usually say "oh that didn't go through I'll manually process that" and approve a few more each time. Incompetence vs maliciousness etc.

    • datlife 42 minutes ago
      >Incompetence vs maliciousness etc.

      Looking at financial reports of the major health insurance stocks in the US makes me wonder if they are really "incompetence".

      Take United HealthCare (UNH) for example, they reported $112.7 billion and net income of $4.11 billion in Q3/2026. That's great amount of revenue and profits to have enough resources to not stay "incompetence". It's not a coincidence.

  • going_undercove 14 minutes ago
    This article is very relevant to me. Just this last Sunday I watched my mother die of melanoma.

    My big takeaway from the whole ordeal is that you need to take a very active role in your own treatment. Unfortunately I was only able to become actively involved in managing my mother's treatment in the last few weeks. What I saw was a clear pattern of (what I'd regard as) negligence. There were so many missed opportunities to provide the care she needed. I came to the sad realisation that if you're not cracking the whip, many doctors will take the path of least resistance, and that in many cases, the only way to get documentation or help as a relative is to be ready to kick up a stink in-person.

    I'd be happy to go into more detail.

  • baoooooooooooo 52 minutes ago
    Meaningful.

    Our friend group went through the support-mode version of this this year and much of the advice rings true.

    To add, a giant shared document that the group of friends had access to in order to take notes. Findings, theories, doctor statements will be shared when the patient isn't in a great place to be taking notes.

    And for anyone reading this that might have someone facing cancer in their lives, go make a nuisance of yourself being present - feel empowered to spend a bit more time than you might initially think is necessary/helpful with them. Facing this stuff alone is when it is at its hardest.

    • emerongi 26 minutes ago
      > go make a nuisance of yourself being present

      I was hospitalised (not cancer) and completely zoinked out of my mind due to sleep deprivation, constant blood loss and being in pain 24/7. People did visit, but I guess they just thought... I have things under control? I wish they had talked to the doctors and asked more questions. In the end I came out of it fine, but I probably would have gotten a better result with someone advocating for me.

      Please go and be a nuisance. As someone with a clear head you will likely be able to understand the topic better, from a more neutral standpoint, and potentially push for the best possible treatment.

    > new folder on my Mac, and after appointments I’d dictate what happened and what the doctor said

    I cannot recommend this enough, including writing down almost every day about symptoms and progress. I didn't have cancer, something else, but it was very valuable to be able to go back and see exactly how long time a symptom has been present and when it disappeared.

    Doctors also seem to react well to being able to be precise in descriptions of what happened when.

    • tredre3 41 minutes ago
      > Doctors also seem to react well to being able to be precise in descriptions of what happened when.

      They do. In my experience they're usually pleasantly surprised when you have dates and timelines rather than "oh I don't know, about a year ago?"

      That being said the reaction differs if you offer a self diagnosis (assisted by google or chatgpt) rather than just symptoms. There will not be pleasantness. It's a toss up between a dismissive "yeah maybe" and "uh uh, did google tell you this?" Many doctors will 100% listen and consider what you say, but in my long life I've learned that offering a self diagnosis must be done very tactfully.

      On one hand it's understandable, us as programmers don't enjoy having a nocoder arrive with "yeah so chatgpt says this is no good" and having to explain to them why they're wrong. On the other hand modern patients do their own research before consulting, so it's worth at least considering what's being said.

    • BrokenCogs 45 minutes ago
      That's because the baseline response doctors are used to goes something like this:

      Doc: "Do you have any other medical conditions besides your {red eye,stomach ache,itchy foot}?"

      Patient: "No."

      Doc: "Are you taking any meds?"

      Patient: "Yes I am currently on chemotherapy for my cancer."

      Doc: "Okay... so you have cancer?"

      Patient: "Yes I have lung cancer."

      Get one of these: https://www.plaud.ai/

      You can do whatevvr you want with the audio files - have them transcribe them, summarize them, hand them to an agent, upload them to your cloud, whatever.

      The standby and talk time is really great on both the pins and the credit card sized versions.

      I have a lot of friends that now use them with elderly parents/their own medical care when they need to really be able to have something automatically record/transcribe the visits.

        • DannyBee 1 minute ago
          Device wise - i never found one as good. However, you have three options with plaud that i'm aware of:

          1. If you want something totally open source: https://github.com/RemiPelloux/OpenPlod

          Local-first Plaud Note Pro recording vault, transcription, and Markdown workspace. Which sounds like what you want.

          2. the Plaud SDK will let you pull from the device and send it wherever you want without touching their servers.

          3. You can also use the mobile app, disable cloud sync, and export each audio file as mp3/wav to your phone/tablet/whatever if you don't want to use #1 or #2.

    Thanks! I'm saving it for hopefully never. I hope your treatment is/was successful!

    have you tried PNC-27 peptide? Another option is focused ultrasound (HIFU) that I would look into before going the traditional route, which might kill you quicker than the cancer itself.

    Frankly, I have the impression that doctors at large put as little care towards their patients’ health as us programmers do towards our software.

      Sure, there are bad apples in medicine just like there are in tech. But knowing many doctors personally, reading this fills me with equal parts frustration at your cynicism and sadness for what they endure.

      What's the difference for a physician today vs. 30 years ago? Among other things, today's physicians struggle because they're being crushed: continuously squeezed by the financialization of their hospital/practice, carrying larger debt, more time spent fighting the insurance machine just to get basic treatments approved. On top of all of that, they are less respected in general and often face outright hostility from patients... all while being paid relatively less than their predecessors.

      The comparison rankles, obviously.

    Oh the privilege.

    Why “when you get” instead of “if you get”. Title assumes we all end up with cancer.
