The anus is 1-1/2 inches long and connects the rectum (lower part of the large intestine) to the outside of the body located at the end of the rectum; its main function is to help solid waste pass from the body. The anus is lined with squamous cells; most cancers develop in those squamous cells. The different types of anal cancer are squamous cell carcinoma, clonogenic carcinoma, adenocarcinoma, basal cell carcinoma, and melanoma of the anus.
