Rectal cancer occurs when tumors form in the lining of the large intestine. It is common in both men and women. Because there may be no symptoms at first, it is important to have screenings often; including colonoscopy and tests for blood in the stool. The cause of rectal cancer is unknown, but the risk of developing it increases as one gets older. Family history of the disease is also a major risk factor.
