Colorectal cancer becomes leading cause of cancer deaths in young Americans

Colorectal cancer has become the leading cause of cancer deaths in Americans under the age of 50, according to recent data. While overall cancer mortality for this age group dropped 44% between 1990 and 2023, colorectal cancer rates have risen by 1.1% annually since 2005.

A 2023 report from the American Cancer Society indicated that 20% of colorectal cancer diagnoses in 2019 were among patients under 55, approximately double the rate recorded in 1995. Medical professionals note that rates of advanced disease in people younger than 50 have increased by about 3% each year.

Researchers are currently investigating potential causes, including sedentary lifestyles, obesity, smoking, heavy alcohol consumption, and diets high in processed meats or low in fiber. While genetics were initially considered, the specific patterns of tumors in younger patients do not align with known inherited conditions like Lynch Syndrome. This shift in demographics has prompted a revision of medical screening guidelines.
