I did Spaceoar, I did not like the shape of it as it only came about 60% down the prostate. I had my urologist review ( Spaceoar recommended ) and a Hopkins trained RO walk through individual dosage to every part of my body. I still think about it but I was at a center of excellence. My point is to make sure and review your CT/MRI and ask questions, it needs to be in properly not just injected.
