Re: Can this be skin cancer?
I would really doubt that it's skin cancer. Stress or trauma can bring about a lot of changes to the body, both internally and externally. If it were skin cancer and it developed that quickly, 10 years later, it would be giving you some problems, more than likely.
You can always get it checked as many times as you like. And if it truly bothers you, talk to a docter about having it removed.
