Hi

My wife was diagnosed with stage 3 toungue cancer had her cancer removed by surgery and did toungue reconstruction on July 2018 and did radio 3 weeks after that.
She did a pet scan 3 month following radio and it came all negative meaning no cancer. After radio she developed a very thin white layer around the flap. Doctor said its not cancer but he would like to remove it anyway by an outpatient procedure. He said he prefer to remove it but cutting it out and not by laser because its a cleaner cut, while lazer might burn it making it a messy process. He said the reason they take it out is to keep the area clean for future monitoring in case anything grow under it.

I am wondering if this is normal to get a white patch that soon after radio and should we be worried about other paches returning or cancer coming back ?

Appreciate ur support
