It is absolutely NO SURPRISE to me that younger and younger people are getting colon and colo-rectal cancer.
The foods and drinks allowed by the FDA to be 'pushed' by marketing are full of carcinogens due to the man-made chemicals and food processing methods used in the foods and drinks that are ALL OVER standard grocery stores and in many restaurants, including especially 'fast food' restaurants. The list of these dangerous chemicals made by the tons daily is much too long to list here, as are the dangerous processes used to make many foods and drinks. Many Americans are doing all they can to avoid these dangerous foods. But many are not. Bottom line: THE FDA IS NOT DOING ITS JOB. The MD's don't mind: They get more sick people to treat and thereby get more income.

By the way, I opted one time to get the Cologuard test instead of a colonoscopy. The Cologuard test was negative. Two yeas later I was diagnosed with stage II colon cancer.
