Which lifestyle factor is listed as a risk factor for colon cancer in the material?

• A. Obesity
• B. Regular exercise
• C. Non-smoking
• D. Balanced diet

Answer: (A)

Obesity is linked to colon cancer risk because excess body fat creates a state of chronic low-grade inflammation and insulin resistance. Higher insulin and IGF-1 levels promote cell growth and can suppress normal cell death, increasing the likelihood that abnormal cells in the colon lining develop into polyps and progress toward cancer. Weight management helps modulate these hormonal and inflammatory signals. In contrast, regular exercise lowers risk by improving insulin sensitivity and reducing inflammation, a balanced diet supports colon health, and not smoking also reduces risk. So obesity is the lifestyle factor listed as a risk in the material.
