I'm a 54 year old man, feel like I'm 25 but unfortunately time catches up with everyone. I had trouble and they took 2 biopsies no results as yet but now I am booked in for a CT Colon scan. What I do know is what to expect there is a blockage in my lower bowel. Has anyone have any advice. I am not deeply worried but perhaps I should be? Any info might put my mind to rest.
