Overview
- A JAMA analysis found that by 2023 colorectal cancer led cancer deaths in Americans under 50, a trend thrust back into view by James Van Der Beek’s death at 48.
- Incidence among adults 20–49 rose from 9.8 to 15.2 per 100,000 between 2000 and 2021, and mortality has been increasing about 1.1% annually since 2005.
- Guidelines from the U.S. Preventive Services Task Force and the American Cancer Society recommend starting routine screening at age 45, with earlier evaluation for symptoms or a first‑degree family history.
- Colonoscopy is the preventive gold standard, while FDA‑approved noninvasive tests detect most cancers but far fewer precancerous polyps and require follow‑up colonoscopy if positive (Cologuard ~92% cancers/~42% polyps; Shield ~83% cancers/~13% polyps).
- Only about 20% of 44–49‑year‑olds are up to date on screening, and doctors warn many younger patients present at later stages because red‑flag symptoms—rectal bleeding, persistent bowel changes, abdominal pain, iron‑deficiency anemia, unexplained weight loss—are overlooked.
