Lee:
To be honest, I don't know what your daughter has, though cancer certainly does not seem likely. (After all, she had something similar 3 years ago . . .)
It's too bad you have to wait 2 months. Isn't there another dermatologist in town? Sometimes calling every day to see if there are any cancellations helps.
Before you have the visit, I'd advise getting a copy of the biopsy report from 3 years ago, so the consultation will be more productive.
Best.
