Warning Signs and Symptoms of Colorectal Cancer

A sign is something you see, such as blood in your stool. It is a clue that something is wrong and you may have a disease. A symptom is usually something you feel like a pain in your abdomen (stomach area) that may also indicate something is wrong. Cancer that starts in different areas of the colon or in the rectum may cause different signs and symptoms. Research shows that when colorectal cancer is detected early, a patient has a much greater chance of complete recovery.

How can colorectal cancers be treated?

These cancers are removed surgically. An operation is usually performed through an abdominal incision. The section of bowel containing the cancer along with the associated blood vessels and lymph nodes are removed. In most cases, the bowel is put back together or reconnected so that normal bowel function is restored.
