Younger Adults Are Missing Early Warning Signs of Colon Cancer

·1 min

Colorectal cancer rates are increasing among adults in their 20s, 30s, and 40s. A scientific review reveals that passing blood in the stool is the most common warning sign. The analysis, based on 81 studies covering nearly 25 million adults under 50, found that rectal bleeding is associated with a fivefold increased risk of colorectal cancer. Abdominal pain, changes in bowel habits, and anemia are other common warning signs. However, young people without a family history of colon cancer are not eligible for colonoscopies until the age of 45. The causes behind the rise in cancer rates are currently unknown. Environmental exposures, changes in gut bacteria, and medication use are being explored as potential factors.
