Rectal Bleeding/ Colon cancer?

  About a month ago, I noticed rectal bleeding but only when I moved my bowels.  It went away until yesterday, it happened again.  I am not in any pain, eat regularly, use the bathroom regularly, and feel completely healthy.  I do not have diarrhea, nor am I constipated.  I am not gay, therefore, there is no anal activity.  I have not been injured in any way.  There is no sign of blood in my boxers either.  Blood drips out like a nose bleed, but only when moving my bowels.  What could be wrong?  What will the doctor do to investigate?

Dear Justin,
If blood is on the surface of the stool (indicative of a lower rectal or anal process), your doctor will do a flexible sigmoidoscopy to texclude processes such as fissures, rectal poylys, hemarrhoidal bleeding.  If blood is mixed with the stool you will require a different more extensive evaluation that will be determined by your age, other symptoms, relative risk for colon polyps/cancer.  The doctor will do either a colonscopy or a flexible sigmoidoscopy and barium enema.
