Hyperplastic polyps are a type of noncancerous (benign) growths found in the colon. They are usually small and make up about 10 to 30 out of 100 colorectal polyps.

Hyperplastic polyps:

• Usually are less than 10 mm (0.4 in.) in size.
• Increase in number as a person ages.
• Do not develop into cancer.

Hyperplastic polyps looks similar to small precancerous (adenomatous) polyps. If there is a question about whether a polyp is adenomatous, your doctor may take a tissue sample (biopsy).
