Colon Cancer Rising Among Younger Adults Raises Alarm

Colorectal cancer is increasingly being diagnosed in people under 50, overturning the long-held belief that it is mainly a disease of older adults. Global attention to this trend grew after actor Chadwick Boseman’s death at 43, highlighting the dangers of late detection in younger patients.

A large international study published in The Lancet Oncology reported rising colorectal cancer rates in younger adults across more than half of the countries analyzed. While cases remain highest in North America and Europe, significant increases have also been seen in parts of Asia, Eastern Europe, and South America.

Researchers link this rise to lifestyle changes, including diets high in processed foods and red meat, physical inactivity, and obesity. Genetic factors also play a role, particularly inherited syndromes such as Lynch syndrome. Experts stress that greater awareness, earlier screening, and improved access to genetic testing are critical to detecting colorectal cancer sooner and reducing deaths among younger adults.
