Lump?

[Jess<3Rats]

Hiya
my girl Angela has a large lump on her left side right under her arm. It feels quite hard and i'm worried if it's some sort of tumor.
Any advice?
Thanks

It's most likely a benign mammary tumour. I'd have it removed asap, those things can grow quite fast.

Ring around and see if you can find a vet that's either done it before or something similar. I find a lot of vets in the UK have very little, if not any, experience with rats
