Anal Cancer Treatment Options. Anal cancer is treated using three methods, used either together or individually: surgery, radiation therapy, and chemotherapy. Treatment depends on the cancer stage, the extent of spread, and the patient’s age and overall health status. [Related post: Anal Cancer Prevention Tips.]
Two types of surgery may be performed. A local resection is surgery where the tumor is cut from the anus, along with some healthy tissue around it. Local resection is done if the cancer is small and has not spread. Tumors that develop in the lower part of the anus can often be removed with local resection. Persons who undergo this procedure, can save their sphincter muscles and are able to control their bowel movements. But because resection can cause anal stenosis or the narrowing of the anal canal and anus due to scar tissue, another surgery is sometimes needed to widen the anus and restore its proper function.
