Polyps of the colon and rectum are most often benign. This means they are not a cancer. You may have one or many polyps. They become more common with age. There are many types of polyps.
Adenomatous polyps are a common type. They are gland-like growths that develop on the mucous membrane that lines the large intestine. They are also called adenomas and are most often one of the following:
When adenomas become cancerous, they are known as adenocarcinomas. Adenocarcinomas are cancers that originate in glandular tissue cells. Adenocarcinoma is the most common type of colorectal cancer.

Polyps bigger than 1 centimeter (cm) have a higher cancer risk than polyps smaller than 1 centimeter. Risk factors include:
A small number of people with polyps may also be linked to some inherited disorders, including:
