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.

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.

The only people who trust clinicians are people who haven't been through the healthcare system. There's the before time and after time. It changes you. Which is why the whole Covid thing was such a wake up call for how blindly people trust doctors. Every field has good people, bad people and mediocre people. Doctors are no different.

Anyway, I would say I actually had relatively positive experience with Thyroid cancer. I had been seeing my Endo for 10 years at that point since I had hypothyroidism. His nurse was on top of everything. Very calm and reassuring during the whole process.

But all my experiences with the healthcare system outside of that were just disappointing. I had RCVS 2 years ago and I was in the ER and the radiologist summarized the report wrong even though he has read it correctly. They were starting me on stroke protocol and giving me these drugs but I had ChatGPT read it and it was like this is wrong. It's supposed to say no significant stenosis in the neck. It actually said significant stenosis in the neck. The dr reported it immediately and the radiologist corrected it. What a shit show. No one could even give me a straight answer on if I could go back to exercising or when I can get off a medication. Every doctor I saw was completely different. Have a few other stories like that pre LLM's. But you have to advocate for yourself. And always double check the doctors with LLM's now a days.

Had a family recently go through unexpected major surgery.

One thing I would mention:

You are not dealing with a monolithic entity with regards to a hospital.

There are really multiple groups with oftentimes competing interests e.g.

- case manager wants you out and home b/c that is the best "score" for the hospital. They also DO NOT want you to qualify for Medicare if you are a senior b/c, again, "score" gets dinged if Medicare gets involved

- surgeons want you out as they don't want you to pick up hospital infection. They want you to go to a rehab facility as that will more likely lead to a good outcome

- the hospitalist wants you to be stable in the short term so will pump you with whatever medications are necessary to get you "back to normal" without addressing any root cause

- the nurses generally care about you as a person as they deal with you the most but oftentimes have the least amount of say over your case

In 2021/2022, I did Google Drive, so I could see it on my phone and other machines.

If this happened now (knock wood) it would be a private GH repo with every test, every image, every receipt, every appointment, every note. Then skills to ingest/OCR/normalize them all into a common format of MD. Point a Claude Code project at it, and fuzzy search it with open questions like "why did Dr. Smith say this" etc.

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.

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.

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.

madrox 11 minutes ago||
What other countries describe is the equivalent of your public health system. If you're willing to pay out of pocket, like you describe, you can have a similar experience in the US. However, that can get expensive quickly since you normally don't have just one appointment with a vascular neurosurgeon.

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 24 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 38 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.

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.

astura 5 minutes ago||
However, many (most?) specialists won't see you without a referral unless they are self pay.
SoftTalker 43 seconds ago||
Yes. They don't have time to deal with hypochondriacs who just show up. Unless you are an existing patient asking for followup, or have a referral, many will not schedule you or will maybe give you an appointent six months from now.

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.

No they didn't.

There are tons of specialists in Canada. You're talking out of your ass.

You’ve dealt with every health system on earth as a patient?

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

Everything you have said is incorrect.

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
InexSquirrel 24 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.

> 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 founding a health tech company and literally visiting myriad health establishments around the world, over the past few decades), the US hospitals and clinics always struck me as the most run down. But as soon as I walked in the boardroom at UHG or HCA, it suddenly all became a lot more glamorous.

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. They also don’t leave citizens destitute for having the unmitigated gall to impose an unexpected health emergency on themselves.

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

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.

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.

Thank you for this. The timing could not be more perfect; my husband was just diagnosed with prostate cancer last week and we have the first meeting with his urologist in less than an hour.

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.

There are a number of startups (and some that already got aqui-hired) working on the problem of "how do i connect with a medical provider who specializes (or at least has seen before) what i have/think i have?" what I've taken away from this is the medical industry is a lot more fragmented than engineers would prefer. It's been a while since I checked but there seem to be at least 30+ startups at least past the series A stage of "fixing" this problem.

Good advice. As someone for whom this is currently relevant, let me add "find a support group".

At least, if it's a common cancer, a group will gather accumulated wisdom and can research better than a single person.

Also, they can help more with practical questions, like financial aid, how to manage sleep and pain, etc.
