Young Adults Face Surge in Rare Appendix Cancer, Scientists Scramble for Answers
A rare appendix cancer is rising sharply among Gen X and Millennials in the U.S., with individuals under 50 now making up about one-third of cases and incidence rising across birth cohorts. Vanderbilt epidemiologist Andreana Holowatyj leads work that notes no standard screening and limited treatments, while exploring possible causes from lifestyle changes (diet, sleep, alcohol) to environmental exposures (pollution, microplastics, water quality) and genetics. Despite the trend, only about 3,000 cases occur annually, but the pattern mirrors the broader rise of cancers in younger adults.
