Cancers That Do Not Kill: Prevalent and Usually Treated Aggressively

If doctors look hard enough, they will find abnormalities. The problem has escalated with improved imaging techniques like ultrasound and scans that allow them to find tiny cancers and precancerous lesions that, in another era, were not seen beyond the autopsy table. Many, if not most, are inconsequential, but no test can definitively sort out the minority that merit treatment. A lot of unnecessary aggressive treatment is the unhappy result.
