Question for Dr. Hope
An_187381 posted:
Dr. Hope,
Have you had any experience with cases of cancer in the small intestines?
Our DR. has told us it is very rare. They have been in touch with the Mayo Clinic. Is there any research you can point us to in order to better understand this condition?
Thanks for your help.
JohnBaltimore responded:
There is a (rare) type of cancer called GIST (gastro Intestinal Stromal Tumor) which can occur anywhere from the stomach to the rectum, and all points in between. If this is your diagnosis, go to for lots more info, including names of experts in this rare cancer.

QUESTION FOR THE DOCTOR! i once had a severe urgency to go to the bathroom and i experienced the most painful bowel movement ever. sometime afterwards I had problems with thin stools and not being able to go to the bathroom at all and pain so severe i could not sit for any period of time .my doctor suggested a colonoscopy which revealed nothing and i then was told to see a surgeon i told him of the symptoms and he prescribed a salve (nitro based) which didn't work. next he performed a sphinxterotomy which revealed a fissure and a fistula. (which was not found during the colonoscopy?) he said he had never encountered a problem where the area was so tight and contracted. this was june 16th! I am still in severe pain and taking a pain pill daily. i t feels as though there is a internal lump in my rectum when i do a self exam(externally of course) can you help?
