Early Warning Signs and Stages of Colon Cancer
Colon cancer or colorectal cancer, is a type of cancer that begins in the cells lining the large intestine (colon). In the early stages of colon cancer, warning signs and symptoms usually don’t occur. Colon cancer usually does not have any signs or symptoms. As the cancer grows and expands it may begin to produce signs and symptoms, for example, diarrhea, constipation, blood in the stool, and narrow or pencil-thin stools.There are four stages of colon cancer; however, The term Stage 0 is sometimes used for a very early cancer that only affects the lining of the intestine. The other stages of colon cancer are stage 1, 2, 3, and 4.
Colon Cancer Prevention
Colorectal cancer is both curable and preventable if it is detected early and completely removed before the cancerous cells metastasize to other parts of the body. Colonoscopy and flexible sigmoidoscopy (along with digital rectal examination and stool occult blood testing) are both effective at preventing colo-rectal cancers and detecting early colo-rectal cancers.
