Surgeon identifies five key factors increasing colorectal cancer risk

The American Cancer Society predicts about 155,000 new colorectal cancer cases in 2025. Colorectal surgeon Cedrek McFadden identified five risk factors: family history, age, diet, lifestyle choices, and chronic conditions. Having a first-degree relative with colorectal cancer can double an individual's risk. The risk increases significantly after age 50, although more younger adults are being diagnosed. Diet plays a role, with processed meats classified as carcinogenic. Lifestyle factors like smoking and obesity also raise risk, as do chronic conditions like Type 2 diabetes and inflammatory bowel diseases.
