@carlsbadguy You are completely correct in your answer. It was how I worded my response that is confusing/wrong. After some thought, this is what I believe my RO was weighing, and I had to do some research before replying. A complication in the procedure of inserting the spacer gel, where a sever life altering complication occurs is about 1-2%. Having radiation without the spacer, where a sever life altering complication occurs is about 1-2%. While the gel has better results for rectum issues, bleeding, diarrhea, they are manageable and not life altering. It was his opinion not to risk a life altering complication from the spacer procedure when compared to the life altering risks associated with not using a spacer from radiation. Hopefully the technology for inserting the gel is getting to be foolproof so that even the manageable inconveniences are not necessary.
