With some types of hereditary syndromes, which lead to an increased risk of colorectal cancer, a person may have hundreds of polyps. For others without a genetic link, just one or a few may grow. No matter the number, it is important to have all polyps removed to prevent cancer.

It is important to know the type and number of polyps your doctor found so this information can be relayed to your first-degree biological relatives. Your personal history of high-risk polyps could impact their cancer risk and when they need to start screening.
