Rectal Cancer Surgery

For people with rectal cancer, surgery is the most common form of treatment. There are three general types of surgery performed to remove rectal cancer: local excision surgery, resection surgery, and resection surgery with colostomy. Even if all the visible cancer is removed during the surgery, some patients may also receive radiation therapy or chemotherapy to kill any remaining cancer cells. While side effects of rectal cancer surgery vary, most patients experience pain in the first few days after the procedure.

Treatment for Rectal Cancer

Rectal Cancer Surgery: An Overview

Surgery (removing the cancer in an operation) is the most common rectal cancer treatment for all stages of the disease. The extent of rectal cancer surgery will depend on the location and size of the tumor, the stage of the cancer, and on the patient's general health.

Rectal Cancer Surgery: Tumor Removal

A doctor may remove the cancer using one of the following types of surgery:

Local excision
Resection
Resection and colostomy.

Local Excision Surgery

If the rectal cancer is found at a very early stage, the doctor may remove it without cutting into the abdomen. If the cancer is found in a polyp (a growth that protrudes from the rectal mucous membrane), the operation is called a polypectomy.

Resection Surgery

If the cancer is larger, the doctor will perform a resection of the rectum (removing the cancer and a small amount of healthy tissue around it). The doctor will then perform an anastomosis (sewing the healthy parts of the rectum together, sewing the remaining rectum to the colon, or sewing the colon to the anus). The lymph nodes near the rectum will also be removed and examined under a microscope to see if they contain cancer.
