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.
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.
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.
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.
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.
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.
> 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".
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.
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.
> 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.
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.
The late Jake Seliger and his widow Bess blogged at length about their experience navigating the medical system after his squamous cell cancer diagnosis. That was in 2023-25 though.
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.
> 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.
> 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.
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.
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.
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.
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.
My only submission will be to consider India, which is fast becoming a hub for medical tourism. You can get any test you want and meet specialists in hours, not even days.
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.

Canada introduced MAID for this reason.
You’ve dealt with every health system on earth as a patient?

Doctors might do the same thing, of course, but at least then there's a real (accountable) person responsible for deciding that "threshold."

This advice can be applied to most things in the life. Expecting the machine in any context to take care of you will likely leave you disappointed.

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."
