Colorectal Cancer Now the Top Cancer Killer for Americans Under 50, Study Finds
A JAMA study analyzing nearly 1.3 million deaths under age 50 from National Cancer Institute data finds colorectal cancer is now the leading cause of cancer death in Americans under 50, with colorectal deaths rising about 1% per year since 1990 while overall under-50 cancer mortality fell about 44% by 2023; experts urge earlier screening for ages 45–49 (only 37% up-to-date) and call for more research to identify drivers behind the rise.
