Which of the following is a recognized risk factor for colorectal cancer?

Polyps in the colon or rectum are a recognized risk factor for colorectal cancer because many cancers start as adenomatous polyps that can accumulate genetic changes over time and progress to invasive cancer if not removed. This is why screening methods like colonoscopy focus on identifying and removing polyps to reduce cancer risk; polypectomy interrupts the progression from a benign lesion to malignancy. Regular exercise, a diet lower in fat, and other healthy lifestyle factors are generally associated with reducing risk rather than increasing it. Younger age is not a risk factor; colorectal cancer risk rises with age, so being young does not increase risk in the same way.
