Anal Cancer

Anal cancer affects the body’s opening at the lower end of the intestines, which allows for the passage of feces. The cells that line the anus are called squamous cells, which are a type of epithelial cell. Both benign and malignant tumors can develop in the anus. Some benign tumors like warts or skin tags can begin as benignly (pre-cancerous conditions) but develop into malignant cancer. Learn more about anal cancer.
