What does Salvage Therapy after Radiation look like?

Hi,
One thing about Proton beam radiation is that you can treat the same general area various times where some X-ray based radiations will max out an area. Proton radiation has a fixed beam length so damage past the cancer site is rarely effected. Other type of X-ray based radiation go completely through your body hitting other organs and tissue.

@clevelandguy Note that for proton radiation treatment they use what’s called a spread-out Bragg peak (SOBP).
Because a single proton beam is very narrow (as you point out), a single narrow proton peak would miss the vast majority of the cancerous cells. Using multiple energy levels treats the entire tissue while sparing nearby organs and tissues.
