All doctors need to do now is develop a "treatment" that boasts a superior survival rate to the untreated. The problem with that sort of treatment is that it doesn't generate enough income for the doctor who scores the lucky diagnosis. Cancer is awesome for doctors because once you net a "cancer patient" you can basically bank on getting everything he owns before he dies in billing secure in the knowledge the dead can't sue for lack of results. Any doctor who is honest will tell you that he can take the rest of the year off once he finds a rube he can label as "cancerous" and start the whole rope-a-dope process going. It's better than the Inquisition but probably just as painful over the long term.
All I have to offer you is Vitamin D. Get it everyday, preferably from sunshine, capsules if it is all you have. If you knew how powerful research shows this stuff to be you'd understand why the doctor is always warning you to stay out of the sun "for god's sake." He means "for my sake, I still have to pay off my Lamborgini."
(Also, get at least 8 hours of deep sleep in a completely blacked-out room each night with no light leaks. Very, very important.)
