I finished 30 treatments of Proton Therapy in December 2024 for a benign meningioma that is quite large. I had very few symptoms related to the radiation. Sore mouth and throat, headaches, and fatigue. But not to a point that was not manageable. Had MRI's in March, tumor was swollen due to radiation, will have more MRI's in August to see what kind of change there is if any.
