colon cancer is treatable with surgery if caught in time with a colonoscopy, but you could die if you don't get screened. colon cancer is the #3 cancer killer, behind breast and lung cancer for women, so you could die if you don't get screened. early colon cancer often has no symptoms, which is why screening is so important, so you could die if you don't get screened. colon cancer is the #3 cancer killer, behind prostate and lung cancer for men, so you could die if you don't get screened. all of the answers are correct, and you could die if you don't have a screening colonoscopy when you reach age 50.
