Teen daughter (15) with malignant melanoma

Has anyone dealt with this before in someone so young? Just got the call with her test results a few minutes ago. I haven’t even told her yet 😫 we don’t see the dermatologist until next Friday so I won’t get any questions answered for either myself or for her before that.

And no judgement please, this was not due to uv exposure. She was predisposed due to a large amount of moles on her body, some of which she was born with, and multiple cafe au lait birthmarks. We knew this was a possibility of times to come already within hours of her birth.
