I just finished(two weeks ago) a round of Chemo and Proton Beam therapy at Loma Linda Medical Center in Califorina.
The only side effects I have experienced at this point is fatigue and some moderate hair loss.
I’m glad to hear it went well. Best wishes going forward.
Both of those side effects are most likely from the Chemo and not the Proton Therapy.
The Proton beam should be very narrow and have mostly localized effects.
Does the picture at the article show the type of machine that they used?
