Anus is the organ present in the extreme end of large intestine and is located just below the rectum. Anus is responsible for eliminating stools from the body. Two muscles known as sphincter muscles are involved in the opening and closing of anus while stool is passed out. The area of the anus will develop inflammation and cause bleeding and itching with pain. The outcome of anal cancer depends on its staging and location and size of the tumor. Anal cancer can be treated and cured if detected in early stages. In advanced stage, cancer would recur even after effective treatments and the survival rate is less.
