I LIKE THE HEADLINE: Cancer Deaths Continue a Steep Decline. And it’s good that cancer deaths are declining, and that’s unlikely to be an artifact of data-gathering. But then there’s this: “Over the past decade, cancer incidence in men has dropped by about 2 percent a year, while it has remained the same in women. There are two reasons, researchers said. First, there has been a decline in male lung cancer because fewer men are smoking, and a decline in colorectal cancer because of men’s increasing use of colonoscopy. Second, from 2008 to 2013, prostate cancer diagnoses declined with the decreasing use of P.S.A. testing.” So fewer diagnoses because of less testing doesn’t sound like progress to me.
