It is believed that colorectal cancers develop over a number of years as the result of changes in the cells of the colon or large intestine and rectum. Though the causes of these changes are not clearly understood, the complex interaction of lifestyle and heredity contributes to the incidence of the disease. Risk factors for colorectal cancer include age as well as environmental and genetic factors. The disease usually occurs in people over the age of 40, and the average age at diagnosis is 60. A polyp is a mass of tissue that grows from a mucous membrane.
Colorectal cancers are highly treatable when diagnosed in the earliest stages.
For more information on treatment for colorectal cancer, please listen to the recording on that in the cancer section of your AudioHealth Library directory. While there is no known way to prevent colorectal cancer, it is thought that people can reduce their risk of getting it by eating a diet that is low in fat and high in fiber. The current average intake of fiber for Americans is only 8 to 12 grams per day.
