Colorectal Cancer 1Monday, March 12, 2012
According to the American Cancer Society, colorectal cancer is one of the leading causes of cancer-related deaths in the United States. However, early diagnosis often leads to a complete cure. Dr. Edward Hill begins a week-long look at colorectal cancer in todays 60 Second Housecall.
Colorectal cancer is cancer that starts in either the colon or the rectum. Colon cancer and rectal cancer have many features in common.
The colon has four sections and cancer can start anywhere in the colon. The wall of each of these sections has several layers of tissues. Cancer starts in the inner layer and grows outward.
Cancer that starts in the different areas of the colon may cause different symptoms. More than 95 percent of colon and rectal cancers are adenocarcinomas. These are cancers of the cells that line the inside of the colon and rectum.
In most cases, colorectal cancer develops slowly over a period of several years. Most of these cancers begin as a polypa growth of tissue that starts in the lining and grows into the center of the colon or rectum. A type of polyp known as an adenoma can become cancerous. Removing the polyp early may prevent it from becoming cancer. This is why screening and early detection can save your life.
