I've had a few people say they would never go thru that procedure, because of the prep needed. Well I've had two friends die slowly of colon cancer because they DIDN'T have the procedure in time.... Trust me, the procedure is well worth doing.
Heck, they weighed me when I went in to have a mole checked for possible skin cancer.... I was like, "Hey... the mole's right there... How heavy do you think it is?!?!?
