Anal cancer is cancer of the anus, which is the opening at the end of the rectum. Anal cancer is different from colorectal cancer. The causes, risk factors, progression, staging, and treatment between the two cancers is different as well. Anal cancer is rare and is much less common than colorectal cancer. According to the American Cancer Society, there are just over 5,000 new cases of anal cancer a year. In comparison, there are over 40,000 new cases of colorectal cancer every year. Anal cancer is a lump of malignant cells that are created by the uncontrolled growth of cells in the anus.
Roughly 50 percent of cases are found before the cancer has spread. When the cancer is found in its early stages, the cancer is highly treatable with a five-year survival rate of 82 percent.
