I had 39 sessions of VMAT (with SpaceOAR) in the summer of 2023. In January 2025 I experienced two consecutive bowel movements with blood in the water. My RO was not concerned since the bleeding quickly stopped. A colonoscopy in November confirmed radiation proctitis in the rectum with no bleeding. Last month I again experienced several bowel movements over 3 days with some blood. There was a bit of straining involved with one session which might have been the reason for the blood. No blood issues since. I’ll let my RO know about the latest bleeding when I see him later this year. In the meantime, I’m not worried about it since I know what is causing it and it’s not happening often.
