I'm so lost and confused

Mimi1971

September 2024 I was diagnosed with melanoma and squamous cell carsanoma. I have mohs surgeries and excisions to remove them. Once the biopsies started taking place and the removal started taking place I began to have severe headaches on the left side of my head along with left ear pain,left jaw pain,and pain in the left side of my throat. I thought it may be an allergic reaction to something used during procedures but to my dismay it wasn't. So due to everything on the left side and the cancer diagnosis I was referred for a CT scan of my head,blood work,and a mammogram. Mammogram shows fibro glandular in the left breast with lymph nodes also showing white. Now Ive got to go and have a repeat mammogram. My throat pain almost feels like strep but strep never develops. Could these symptoms be related to the mammogram results? Does this result mean it could be cancer? I can't seem to hold my weight. Since September I've lost 30 lbs without any difference in exercise and no change in diet either.

I just need some directions on what to do or what to prepare for please.
