What is Colorectal Cancer?
Colorectal cancer is a type of cancer that starts in the colon or rectum. The colon and rectum are parts of the large intestine, which is the lower part of the digestive system. It develops when abnormal cells in the lining of the colon or rectum grow uncontrollably and form a tumor.
The disease typically starts as small, non-cancerous growths called polyps. Over time, some polyps can become cancerous if they are not removed. If the cancer is not detected and treated early, it can spread to other parts of the body and become more difficult to treat.
