I got a call from the vet yesterday with the histopathology results - the big bump was an apocrine cyst, which won't reoccur.. unfortunately the little bumps are papillomas, tiny benign tumors which may get larger and get uncomfortable in the future. So those might have to come off, but that's not a big deal and they won't spread beyond her skin. She also had a small bump removed from her eyelid but the cells were not malformed in any way, so she probably got something in her eye at some point and it caused a little callousing.
Yay! She will be OK.. she might just look a little bumpier in the future but it isn't pathologic. Which is good. More yay!
