This doesn’t have to happen. About 95 per cent of colon cancers begin in existing polyps. If the polyps are removed, you won’t have to die from this malignancy.
These soft, fleshy growths originate on the inside lining of the bowel. It’s estimated that one person in three over the age of 50 has one or more polyps.
