Colon Cancer or Colorectal Cancer

Colon Cancer or Colorectal Cancer (CRC) is a disease of the large bowel, it is a type of cancer that originates from the rectum or colon, also known as colon cancer. Your colon, cecum, rectum and anus make up the large intestine Figure 1. The ileocecal valve, located at the opening between the ileum and the large intestine, controls the flow of chyme from the small intestine to the large intestine.

Colon cancer occurs mainly in the large intestine where waste materials from digestion begin to build up, the colon absorbs vitamins and nutrients from the digested food that passes through. It usually starts when abnormal cells form out of control, invading the rectum's wall and neighboring tissue. CRC is one of the most common types of cancer among adults. It is also one of the deadliest, with the vast majority of cases occurring in men. Although CRC is usually found in men, it is also possible for women to develop this disease.
