@celia16 Thank you so much. Things have needed to move so quickly that we haven't had a 2nd opinion. I was looking into the Mayo Clinic. Have you had any experience with the targeted Proton beam. I imagine, we don't have that technology here in Boise but I'll be asking. It's hard to watch your child suffer. It still feels like it should be us as his parents. This is my first experience with a support group. I'd welcome any suggestions on support or finding sarcoma experts. I do trust our doctors so far. That has been a surgery and meeting one pediatric oncologist. They have a whole team of pediatric oncologist.
