Colon polyps are small growths that occur in the lining of the bowel. They can vary in size. There are two types of polyps: hyperplastic, which is not a risk for cancer, and adenoma, which is thought to be the source of almost all colon cancers. However, most adenomas never become cancerous.
The cause of colon polyps is unknown. Some believe that a high-fat, low-fiber diet contributes to the likelihood of developing polyps. There may be a genetic risk to developing polyps as well.
The best way to detect polyps is through a regular screening colonoscopy.
If found during a colonoscopy, they can be removed. They are then examined under a microscope to determine what type they are and whether or not they are cancerous.
