Hello, thanks for your question today! I am Dr. Drew, and I am a licensed veterinarian. I'll be happy to help you in any way I can.
Rather than planning on having multiple lumps removed,
I'd suggest having them all tested via a fine-needle aspirate, to determine which ones may have suspicious-appearing cells within them,
which could indicate cancer.
If some of the lumps are found to be benign, then surgical removal is still an option, but not required.
It's not really possible to determine how serious any given lump might be, just by looking at it,
so I'd suggest asking your veterinarian about the fine-needle aspirate testing.
Thank you, XXXXX XXXXX take her to our local vet and get them tested.
