Basil cell on my back,

I had a mole removed from my upper back, last year? It was right under my bra strap, so was getting irritated a lot. No problem, the dr just burned it off. And never heard anything else about. I was diagnosed with anal cancer this year. Just finished my treatments about 3 weeks. The dr send me to the dermatoligist  some moles I had on my face. So I go in and the nurse asks me did ever follow up from my last visit, where they found basil cell on that one! I told her I was never notified anything about it. Luckily they got the whole thing and has healed very well. But that just surprised the heck out of me.
