Ok so it looks like I may be able to access SBRT if I categorically refuse surgery
and dig my heels in.
However, two ROs and two surgeons so far have said that in the case of treatment failure, options become much more limited. This is also relevant in case of recurrence or of any LN or SV involvement after RT as opposed to RP. There does not seem to be any involvement yet from biopsy TRUS images though they said they couldn't tell for sure until after surgery and tests for positive margins.
Just a reminder:
7mm with signs of possible capsule contact (not yet extracapsular apparently)
42 years old
I'm being told that I need to act very soon.
