Hello,

My grandmother was under heavy chemotherapy (cytoxan, taxotere) and radiation for stage 4 breast cancer. The first thing that became apparent after her first round of radiation is that moles on her left arm started to change. The changes continued and now she has a growths on her left cheek and shoulder, too and she is supposed to see a dermatologist at the end of May.

But before dermatologist confirms it, I was wondering is it possible that her previous chemotherapy and radiation have caused her to develop melanoma or squamous cell carcinoma?
