Colon Polyps - Overview

Colon polyps are growths on the lining of the colon or rectum. The colon and the rectum are parts of the large intestine. It is all part of the digestive system.

The two most common kinds of polyp are:

  • Adenomatous polyps—can become larger over time and may develop into cancer
  • Hyperplastic polyps—do not increase in size and only rarely become cancerous

Causes

The cause of colon polyps is unknown. It may be partly due to hereditary factors. There is a genetic condition called polyposis coli. It causes thousands of adenomatous polyps throughout the bowel.

Risk Factors 

Risk factors for colon polyps include:

Symptoms

Symptoms are often not present. Polyps are only found during an endoscopy or x-ray. If symptoms are present, they can include:

  • Diarrhea, constipation, and/or bloating that lasts over a period of time
  • Abdominal pain, rarely

Diagnosis

The doctor will ask about your symptoms and medical history. A physical exam will be done. Tests may include:

  • Your doctor may need to examine your rectum and colon and waste products. This can be done with:
  • You may need to have pictures taken of your colon. This can be done with a barium enema and x-ray.
  • You may need to have tissue samples tested for cancer cells. This can be done with a biopsy.

Treatment

Depending on the size of the polyp, it may be removed. Large polyps are at high risk for becoming cancerous. They should be removed. Usually, polyps can be removed by colonoscopy.

If the polyps are very large, you may need to have surgery to have them removed. Your doctor may send the tissue from the removed polyps to be tested for cancer.
