New diagnosis, slow process, concerned

I moved to NC mid-September to be with my mom. She had just had a “bump” removed from her nose. On 10/5/21, she got a call telling her it was melanoma and that she needed to see a plastic surgeon. They called 10/6 and scheduled surgery for 11/9 with the only information she got being that she had to come alone for this out-patient surgery and that they may have to remove part of her nose. No one has discussed oncology, staging, treatment options or anything else. Her dermatologist who was initially concerned and chose to do the biopsy said after the plastic surgeon finished with her, he could check for more areas of concern as she has tons of large moles of various colors and shapes on her back. I’m anxious about her prognosis and treatment plan and feel that two months from biopsy to surgery is too long to wait. Wondering if that’s normal, and I’m pushy or if I should be doing more to advocate for her. I also just started a new job which is much more time intensive than I expected and is causing added stress. Any direction on where to go for information aobut what should happen, treatment options, etc. would be much appreciated
