my neighbor was diagnosed with skin cancer a few years back. They did surgery and treatment and he's fine today. He's just very careful about the sun now.
I'm sure you will be fine too.
Good luck and make sure to tell the doctor everything that you're feeling. They can't read your mind, so you have to tell them everything, no matter how silly you might think it is.
My sister and mom are survivors of different forms of cancer - one of them the most virulent one out there, and they're both alive to talk about it today.
