Hi @baylaurel- sure - clearly I'm not an oncologist but at MGH they felt proton beam was not the "best" treatment based on my cancer - which could include location, size, tumor markers, my age (58yrs), stage 1, no nodes, 1.8cm. I wish I had more details but my point is I would not hold up treatment if you feel confident with your current radiation oncologist as I really think if they felt proton beam was the best strategy (like in pediatric brain tumors, spine) they would defer to this second opinion. However if it makes you feel better to at least get a consult like I did I would certainly pursue. I hope this helps and good luck. Keep us posted! xoxo
