sqaumos cell and melanoma

markie_maypow

I just received notice that a biopsy confirmed my second occurrence of squamos cell. I had my first tumor removed from my forehead January, 2013 and this latest tumior is near my left ear. I have surgery scheduled for January, 2015. I have read alot about the susceptibility of recurrence but my question is whether anyone has read about the chances of future biopsies showing melanoma. Any information is appreciated.
