Colorectal cancer is a cancer of the colon and rectum. Women who have never used hormone replacement therapy and are postmenopausal have a higher risk of colon, but not rectal cancer, than women who are pre-menopausal and of the same age, and dietary habits.

Non cancerous clumps of cells called adenomatous polyps are usually the way most cases of colon cancer starts. Cancer of the colon and rectum is a malignant tumor arising from the inner wall of the large intestine. Changes in bowel habits, persisting cramping, gas or abdominal pain, blood in your stool, may be the signs and symptoms of colon cancer. It is best to get regular colon cancer screenings, since colon cancer can grow for years without causing any symptoms.

It is important that all men and women age 50 and above should have a colon cancer screening as this may help prevent colorectal cancer by finding pre-cancerous polyps so they can be removed before they turn into cancer. The preferred procedure for normal risk individuals is a screening colonoscopy every 10 years, or annual stool test for blood and a flexible sigmoidoscopic exam every three to five years.

For those with a personal history of colorectal cancer or adenomatous polyps; non-hereditary polyposis; pre-disposing condition e.g. inflammatory bowel disease; family history of colorectal cancer; screening colonscopy needs to be available at frequent intervals.

Recent research suggests that a high fiber low-fast diet plays a role in the prevention of colorectal cancer. Although the exact cause of colorectal cancer is not known, it is possible to prevent many colon cancers through diet and exercise.
