There are at least a hundred thousand cases of colon cancer diagnosed yearly in the United States. The good news, however, is that the incidence of this disease and the mortality rate has slightly decreased in recent years. This could either be a result of early colon cancer diagnosis or treatment of the disease, or a combination of both.
In the case of other cancers, tests look for small, malignant lesions. Tests for colon cancer diagnosis, however, search for pre-malignant, benign polyps. This can be almost a hundred percent effective in preventing colon cancer development. Because early colon cancer diagnosis often leads to a complete cure, it is very important, especially for those who are at high risk for colon cancer, that they get regular screening.
