My RO did not explain that about the colon and blood vessels. All they told me is that I would tolerate SBRT better. I had the cyberknife SBRT. I was thinking about Brachy before SBRT. Now, I’m not so sure I made the correct decision. I use the prep H. I have hydrocortisone suppositories. Takin Metamucil. Doing sitz. I’m ready for this torment to be over.
