Does everyone show colon polyps symptoms?

NO they don't: Most people with colon polyps have no symptoms! that's why it is so important for people to get screened when appropriate. Generally when you are 50, and maybe sooner if there is a family history of colon polyps.

Usually not: Most polyps unless they are cancerous or partially obstructing the colon do not cause symptoms. African american patients should start screening colonoscopy at the age of 45, otherwise start at the age of 50 or younger if you have a family history of colon cancer.

Cancer: Cancer is now the number 1 (número uno) cause of death age 60-79 in the US, more than cardiovascular disease. Lung cancer by far the most deadly cancer (more than colon, breast, ovarian & prostate all together). Please ask for cancer screening: colonoscopy, Pap, mammogram and PSA. No excuse not to be screened specially after age 50, even younger depending on family history and type of cancer.
