Colon cancer, also known as bowel cancer, is a cancer of the colon or the large intestine which is found in the lower part of the digestive system. Rectal cancer, on the other hand, is a type of cancer that affects the end parts of the colon.

The collective name for these types of cancer is colorectal cancers. Nevertheless, whether it affects the colon or rectum, colorectal cancers grow little by little in a period of up to ten years before spreading and starting to affect other parts of the body.

Some of the common risk factors for colon cancer include; race, age, cancer history in a family, long-standing ulcerative colitis and colon polyps. Additionally, colorectal cancers often develop from polyps or growths. Regardless, the only way to prevent or remedy colorectal cancer is through the removal of the tumor tissues.

Colon cancer or colorectal cancers may also form if cells grow uncontrollably in the large intestines. Quite often, these cancers instigate from tiny benign (noncancerous) tumors known as adenomatous polyps which form on the large intestines inner walls.

Anemia is caused by low levels of red blood cells in our body. Furthermore, colon cancer may cause anemia due to an infinitesimal amount of chronic blood cells in our stool. This bleeding leads to the loss of iron in the red blood cells thus depleting the iron stored in the body.(2)

Women, on the other hand, experience a shortage of iron during their menstruation. However, for men, it is not common, and there is the need for a further check-up by a physician to determine the deficiency.

  • Blood in your stool (rectal bleeding)
