Anal cancer is a rare type of cancer. The anus is where stool leaves your body when you go to the bathroom. It is made up of your outer layers of skin and the end of your large intestine. Anal cancer is a disease in which cancer cells form in the tissues of the anus. Colorectal cancer, also called colon cancer or large bowel cancer, includes cancerous growths in the colon, rectum and appendix.

Dear Amy, I have located the following information for you: ANAL CANCER Anal cancer is a type of cancer which arises from the anus, the distal orifice of the gastrointestinal tract. It is a distinct entity from the more common colorectal cancer. The etiology, risk factors, clinical progression, staging, and treatment are all different. Anal cancer is typically a squamous cell carcinoma that arises near the squamocolumnar junction. Symptoms of anal cancer include bloating and change in bowel habits, sporadic bright red rectal bleeding accompanied with uncontrollable itching at the opening of the anus, and low energy and fatigue, probably due the nature of the disease. Women may experience lower back pain due to pressure the tumor exerts on the vagina, and vaginal dryness. COLON CANCER Colorectal cancer, also called colon cancer or large bowel cancer, includes cancerous growths in the colon, rectum and appendix. With 655,000 deaths worldwide per year, it is the third most common form of cancer and the second leading cause of cancer-related death in the Western world.[1] Many colorectal cancers are thought to arise from adenomatous polyps in the colon. These mushroom-like growths are usually benign, but some may develop into cancer over time. The majority of the time, the diagnosis of localized colon cancer is through colonoscopy. Therapy is usually through surgery, which in many cases is followed by chemotherapy. The symptoms of colorectal cancer depend on the location of tumor in bowel and whether it has spread to elsewhere in the body (metastasis). Most of the symptoms may occur in other diseases as well, and hence none of the symptoms mentioned here is diagnostic of colorectal cancer. Symptoms and signs are divided into local, constitutional (affecting the whole body) and metastatic (caused by spread to other organs). In other words, anal cancer would be a cancerous tumor located at or near the anus or the opening to the bowel. Colon cancer would be a cancerous tumor located somewhere in the bowel including cancerous growths in the colon, rectum and appendix. Hope this helps you immensley. Dolores
