The anus is the body’s opening at the lower end of the intestines. The anus is about an inch and a half long and connects the lower part of the large intestine to the outside of the body. It opens to allow the passage of stool (feces) during a bowel movement. It is lined with cells that are like the cells lining the bladder, vagina, urethra, and other places in the body. These cells are called squamous cells.
Many kinds of tumors can grow in the anus. Not all of these tumors are cancers -- some are benign, which means they are not cancer. There are also some growths that start off as benign but over time can change into cancer. These are called pre-cancerous conditions. A common term for these potentially pre-cancerous conditions is dysplasia. Some warts, for example, contain areas of dysplasia that can develop into cancer. Benign tumors include some kinds of warts and skin tags (small pieces of skin that hang loose from the body).
