My brother just died of Skin cancer.
He didn't have melanoma. He had either basal or squamos (can't remember).
He had it for over 20 years. It slowly ate away at his face and head. Finally, it caused him to lose his ear, then his eyesight, then it went to his brain and he died.
It was horrible!
You described squamas cell. It is nearly always treatable if not ignored.
