@justwow I am 8.5 weeks out from both chemotherapy and 7 weeks/35 treatments of proton therapy for stage 2 tonsil cancer with one lymph node affected on each side of my neck. Surgery was not recommended. lost most all my taste by week 3. I am just now regaining some taste. I still do not have much of any saliva. I experienced mouth sores and some associated pain. The radiation did cause the skin on the outside of my neck to burn and scab around the 5th week of treatment. I followed my team's skin care directions and it healed by the end of treatment and has been and still is perfectly normal in appearance. I do not believe that you should experience any scarring from proton treatments.
