Well i got my tests back and all were perfectly normal. CBC was perfect and abdominal Ct Scan was perfect, they also scanned the kidneys and liver. I have been having constant abdominal discomfort around the belly button area for over a year and my gastro said i should have a colonscopy. I am 21 years old good health except for this abdominal discomfort. What could the colonscopy show that the CT scan could not? My doc said cancer is allmost certainly ruled out, soo my question is what other things could my problem be? Thanks Alot Jason
