Colorectal cancer is a deadly carcinoma of the colon or rectum. It is the most commonly diagnosed cancer in the United States,
with over 100,000 cases of colon or rectal cancer reported each year.
It has been found in studies that a calcium-rich diet and calcium supplements have a protective effect against colorectal cancer in the long run. To this end, doctors recommend regular intake of calcium supplements, as well as physical activity, and a well-balanced diet.
