Lately, it’s been good news/bad news on the colorectal-cancer front. Let’s share the good news first: The rate of this cancer has been dropping since the 1980s, mostly due to colonoscopies and other screening tests for people 50+ that allow doctors to spot and remove polyps that can turn malignant. The bad news? Rates have been climbing among Millennials (roughly 23 to 38 years old in 2019) and Gen X-ers (about 39 to 54). And not just by a little. Compared to 29-year-old Baby Boomers in 1979, adults that age today have twice the risk of colon cancer and quadruple the risk of rectal cancer.
