Just my experience but I have never found the medical industry useful for health. I have found they mostly tinker with feedback loops to give the illusion of health.
Eating right, exercise, supplementation of the things I am missing from my diet, clean air, avoiding chronic stressful situations and people are the only things I have found to benefit me. But that's just my own anecdotal experience. (n=1)
At minimum medical industry is good for providing various measurements regarding the state of your health and environment. This can get quite pricey quite fast.
