yes it could. Also if you have had radiation for your prostate, you might bleed in your urinary tract including unable to urinate (blocked by blood clots because the radiation can cause bleeding from the lining of the bladder).
Also you can bleed from the lining of your colon or rectum, because the radiation can effect the parts of the body near the prostate. It can take years to manifest the effects of radiation. Mine took 3, and 4 and half years. i have had bleeding from both areas.
There has been great progress in external beam radiation for prostate cancer in recent years. The beam is CT guided in real time sparing adjacent tissue.
