Healthy cells grow and divide in an orderly way to keep your body functioning normally. But when a cell's DNA is damaged and becomes cancerous, cells continue to divide — even when new cells aren't needed. As the cells accumulate, they form a tumor.

If a polyp or suspicious-looking area of tissue is found, the doctor can also take samples of tissue from these areas with instruments inserted in the colonoscope.
