Does this sound like fissure or hemorrhoid? I have occasional blood on tissue after using the bathroom. I have had this on and off for 10 years.A barium enema 2 years ago did not find anything. I have seen countless drs.they say fissure. I was sent to a surgeon in April who said I did not have a fissure! Ihave had several "rectal" exams by drs in the last year who do not "feel" anything abnormal.So,I need someone to tell me this is probably not rectal cancer,right ?if I have been checked by several drs.
