My father is constantly going to the bathroom, bowel movements, loose stools, defecating in his pants, non-stop, when he goes to the store, out to eat, comes to my house, goes to the chiropractor. As far as I know there is no blood and he has no pain, but will not call and discuss this with his doctor. He, also, drinks straight up vodka, like a pint a day. Could he have colon or bowel cancer?
