When you get salvage radiation, they give you the maximum radiation for that area for life. They can’t go back into that area with radiation. They can use SBRT to zap metastasis in other areas.

A few doctors have recommended waiting until the PSMA pet scan shows something. Dr’s Kwon and Scholz Seem to believe in that. They don’t wait for it to get to two however, if your PSA hits one, the PSMA PET scan works quite well.
