Dea Samalex,
It may not be as bad as you are expecting. Fingers crossed it is at least early.
You may feel better when you actually know more details. And possibly a plan too.
You do seem to have had a lot thrown at you, caring and helping others.
I was 61 on diagnosis, in Feb 2020. I had the Mastectomy, Chemo, R/T and daily medications for 5-10 yrs.
I managed the treatments quite well. The response people have is very variable.
My Breast surgeon and Oncologist, were excellent letting me know all I needed.
After your biopsy result, if it is cancerous. You will be most likely ordered a whole body bone scan and Abdominal and Chest
CT scan, to see if there has been spread to other areas. And of course if you have the lumps removed, you will have more information. One step at a time. I'm sure you will have questions. Keep paper and pen handy, and write them down as they occur to you.
I wish you all the best.
