Wow! -- I've been asking a score of providers and patients over a year-plus about the differences between "SBRT and Proton Therapy," and nobody before has thought to tell me that Proton is *a FORM of* SBRT!

So then, I now wonder, if I am going to ask providers questions about this kind radiation therapy, how do I *differentiate* between asking about Photon SBRT Therapy and whatever the other form of SBRT radiation therapy is called/designated: Photon SBRT vs. Proton SBRT?
