Polyp Growth Rates

Cancerous polyps tend to grow slowly. It is estimated that the polyp dwell time, the time needed for a small adenoma to transform into a cancer, may be on average 10 years (17). Evidence from the heyday of barium enema examinations indicates that most polyps do not grow or grow very slowly (18).

Does location of colon polyps matter?

For all the colon segments, the presence of polyps at baseline colonoscopy confers a significant risk for recurrence in the same location at surveillance colonoscopy. This risk is about four times higher in the distal colon, closely followed by the proximal colon.
