My mother was treated for skin cancer on her forehead some years hago. She had radium treatment but it cleared it up.
My father who spent most of his life outside had some suspect changes on his face. They operated cutting his face from ear to nose on both sides. He was in his 80 s at the time and it was done as day surgery. He got fed up having to wait for my sister to pick him up so he caught a bus home. The Drs were talking of skin grafting to get it to heal but a week later it was al closed up. The changes were positive for cancer cells.
As said, no one can say just by looking but tests should be done ASAP.
