Listen to the Specialist but remember that the specialist will have a specialist's perspective.
If you can afford Proton Beam at Loma Linda or M.D. Anderson, I would definitely look into it. Their specialists will likely tell you more about this promising procedure than anyone else. Still, don't just jump at this because it is new. Evaluate your options.
Only you can make an informed decision that involves everything about you, your family, your overall health, the complications of your fight, how far you can or want to travel, and so much more.
I would examine each of the (4?) alternatives you are considering with a consultation from the best specialist in that field practically available! Then make a decision. Pray about it for a day or two. (To me, a "7" says don't wait around too long - make a decision!) Then get a second opinion from another source (Johns Hopkins, Cancer Centers, etc.).
