Looking for tips on managing Radiation-induced proctitis

I completed radiation 6 months ago and now, out of the blue, I've experienced some pretty significant rectal bleeding. (Everything else is good -PSA undetectable and just a little fatigue from the ADT.) Im told this is not unexpected,
yet it is a bit startling. Just looking for others with similar experience.

I have to be careful here and want you to know this information came from my R/O and team at UFHPTI.

They would not do the radiation treatments unless I had had a colonoscopy within a year. The reason is that the radiation can cause damage to your colon and having a colonoscopy after radiation was not advised.

I just wanted to pass this along and suggest you talk to your colonoscopy specialist about this.

I think your Space/Oar movement may have added (but just a feeling) to your colon being radiation. The time frame for bleeding told to me was not until some time had passed. What I was told was that the small blood vessels can be damaged during radiation in colon. They will die and new vessels are formed. When the new vessels are formed they are vulnerable and can be easily damaged and bleeding will occur.

Thus, the extended time frame for this is not right after radiation but later on. The new blood vessels will eventually become stronger, and the bleeding stops but this takes time. Again, this is not my information but from my radiation treatment team.

Please check on having a colonoscopy after you have had radiation and also you are having bleeding. If the colonoscopy is to address the bleeding probably you have told them about radiation, and they are trying to get the bleeding stopped. But I mentioned is just as a precaution.
GOOD LUCK!!

After I posted my reply I was thinking maybe they are doing colonoscopy to fix the bleeding.

I was just (prior post) passing on the concerned my R/O had with doing colonoscopies after radiation treatments as colon will have some damage and easily injured. But you needed to address the bleeding not just a routine colonoscopy.

Did you have proton or photon radiation? Did you have the high dose radiation (short term treatments) or the low dose long term treatments?

Although still going through a lot of studies and different opinions the photon radiation since it passes through the entire body versus proton stopping at predetermined spot and not passing through body has been shown to have diferent radiation damage to colon and other organs tissues.

My PCP is really doing a lot of reearch on this and many studies are looking at if Space/Oar is really justified to help reduce radiation damage to colon. He said also looking at the practice of drinking water prior to radiation to move bladder away from prostrate.

What he is saying is the study is to make getting the treatments the best for patients and to ensure the additional precautions that are done now are showing long term benefts. I think those studies are good but for me I wanted to take as much precautions as I could not so I chose proton not photon radiation, get the Space/Oar and drink the water.

No, I was one of the freaks who had the symptoms mostly emerge a year later.

But the complication in my case is that the metastasis compressed my spinal cord and left me paraplegic in 2021. I've since recovered a lot of my mobility and sensation below the ribs (not all of it). So it's possible that I just couldn't feel the proctitis and cystitis in 2022, and became aware of it in 2023 as sensation improved.
