These signs and symptoms can be caused by cancer or by a number of other conditions. It is important to talk to your doctor if you have any of these signs and symptoms and to screen for colon cancer even if you don't. If the polyps that lead to the cancer are detected and removed, colon cancer can often be prevented. If colon cancer is detected early, it is up to 90% curable.
