For example, and I’ll pull numbers out of the air, because the news piece came out a few years ago, but there was breathless reportage that “breast cancer diagnoses are up over thirty percent from forty years ago!” and implied that some dreadful thing in the environment was causing breast cancer. To which the person in my family who works in a related medical field snorted and said something that rhymes with “pulpit.” What has happened is that 1) mammography has become cheap and common, and 2) because of that and better technology and imaging, more and more tumors are found that would not have been caught before because of their tiny size. Many of those are very slow-growing, most are not malignant at the time of discovery and are tracked but not removed.
