            Generally....A black tarry stool can indicate bleeding far up the colon. Bright red is usually hemorrhoidal, or near the end of the trac (rectal area). I know this mostly from colonoscopy literature that I have received in the past. Something in the diet can also cause this, but usually not for three days. I would get it checked. A family doctor can usually do a hemoccult test in his office, and they are inexpensive. A colonoscopy is more expensive, but is a major lifesaver . Begin with a family doc. Way less expensive than the oncologist. The GI trac is not a popular place for lymphoma to migrate to, but it is possible. max .

            Colonoscopy....Hi Carol, First thing that came to my mind was...are you taking any kind of new medicine? About 10 years ago my doctor put me on celebrex and after only two doses I had blood in my stool. He sent me for a colonoscopy which came back fine, and then had me stop the celebrex. Once I quit taking the celebrex I didn't have anymore bloody stools. Please call your doctor and get this checked out. Let us know what you find out. Best wishes...Sue

I find that any little thing that comes up I get so anxious. Hope that lessens in time. Thans again for the response.
