Colon Cancer (cont.)

Medical Treatment

The primary treatment of colon cancer is to surgically remove part of your colon. Suggestive polyps, if few in number, may be removed during colonoscopy.

Chemotherapy after surgery can improve your likelihood of being cured if your colon cancer has spread to nearby lymph nodes.

Radiation treatment after surgery does not improve cure rates in people with colon cancer, but it is important for people with rectal cancer.

  • Given before surgery, radiation may reduce tumor size. This can improve the chances that the tumor will be removed successfully.
  • Radiation before surgery also appears to reduce the risk of the cancer coming back after treatment.
  • Radiation plus chemotherapy before or after surgery for rectal cancer can improve the likelihood that the treatment will be curative.
