If they can do SBRT radiation, they can get it over in five sessions. There are a lot of radiation oncologist that do that instead of IMRT with 4 to 8 weeks.

They could also do the brachytherapy if still necessary, They can actually do that first.

You may not need it if you have SBRT.

You probably need to speak to another RO. With a Gleason score of seven SBRT is very common. My brother had it, it worked great. I know somebody with a Gleason eight that had it and is still fine 17 years later..
