Treatment of Cancer of the colon, rectum or bowel
Colorectal cancer is usually treated by a surgical operation to remove the affected segment of the bowel. The free ends are then joined together, if this is possible. It may be necessary to remove the tumour and some of the surrounding tissue.
When the cancer is very low in the rectum, the anal canal must also be removed to prevent the cancer coming back. In that case an artificial opening (colostomy) is necessary, bringing the bowel out through the front wall of the abdomen.
Radiotherapy can be used to treat symptoms and relieve pain. Chemotherapy is sometimes prescribed after surgery, to prevent recurrence. It may also be used to relieve symptoms in advanced cases of colorectal cancer.
