I'm sure you mean well, but this type of thinking really bothers me.
For example, many of us here on HN, possess the critical reasoning skills to determine snake oil from a credible research lab. Given that there are almost no practicing oncologists present, we'd all likely qualify as lay people.
However the central issue is a medical doctor is not even qualified enough to choose, due to malpractice liability. On top of that even a specialist can find difficulty prescribing experimental treatment lawfully, unless it's part of an FDA trial. This is in addition to the incentives drug companies push. [1]
I speak from first hand experience dealing with Psoriatic Arthritis and establishment CYA (cover your ass) thinking. After spending $1000+ per month on Anti-TNF blockers [2], I'm doing just fine on lifestyle changes and have seen no disease progression after 3 years of being off meds. I wouldn't bother mentioning it if it weren't for the thousands of credible patient stories that point to fixing what we eat as a means to being healthy. Yet the paradigm for the last 30 years is one of treatment, not prevention.
Guess which makes more money for Pfizer, GSK etc? Hint: it's not vaccines (prevention). Chronic treatment (autoimmune, psych drugs, cvd etc) are dominating the top 10 sales charts. [3]
I would feel incredibly angry and upset if myself or someone close to me, were in a position to try an experimental cancer treatment, but were unable to, because of regulatory snakes and ladders.
I'm not saying the FDA is useless or provides no public benefit, but I would question the wisdom behind entrusting authority of one's life, to a single decision making body.
