Thank you very much for your reply. I appreciate it.
When I picked up the test results, I immediately went to see my father's doctor (and by the way he is not a cancer specialist). He told me that my father is ok now but it wouldn't have been good if the spot hadn't been removed. That's the only thing he kept saying. But somehow that's not a sufficient answer for me. My dad talked to him the following day too and the doctor told him the same thing.
I saw another doctor and he told me that my dad should use a cream (which he did last summer) and that he should use a hat as well (which my father again did) and stay out of sun. This doctor thinks that the cancer won't reoccur, since it has been completely removed. It said so in the test results. This doctor added one more thing; he doesn't seem pleased with the fact that my father's doctor operated him while that spot was inflamed. The test results described the removed tissue as inflammed with pus. According to him, my father's doctor should have waited for a while with the operation.
All this didn't calm me down. I am really worried, and so is my father, of course. My father keeps telling me that he feels something, like itching, on his entire face. He is afraid that he might be getting those red spots all over his face.
I am also very worried because my great-grandfather (my father's grandfather) died of lung cancer and my grandfather (my father's father) of stomach cancer. My grandmother (my father's mother) has red spots on her face and they were removed and some of them reappeared but the test results showed no sign of cancer stating that they are spots that old people get/have.
