I had proton radiation at Loma Linda and will bump my thread to the top for you.
The procedure is totally noninvasive with minimal if any side effects and Loma Linda is a wonderful, caring and very proficient place to go for treatment. Info can be gotten at www.protonbob.com.
Hope you will find the answers you are looking for and good luck.
