hi i have a pet rat (female) who has lost quite a lot of fur, and has now developed a red lump on the side of her stomach.
JA: Hi there. I'll do all I can to help. When did you first notice the rat had this lump?
Customer: i noticed last week, and i called my vet and they said just to keep an eye on it.
JA: What's the rat's name and age?
Customer: Ivy and she’s nearly 1
JA: Is there anything else the Vet should know?
Customer: i noticed she has scratched the lump this evening which has caused it to bleed a little.

these are from last week.

the lump has gotten bigger since then.

I see the alopecia and small area of excoriated skin. Regrettably, I can't get a good look at the skin because it's covered with her haircoat. You can't monitor (only) a lump she has scratched as they're often malignant and painful resulting in her scratching. The most common tumor of rats is the mammary fibroadenoma but these aren't painful unless they ulcerate after growing to an enormous size.

The area of her alopecia is most likely from self-induced licking perhaps due to referred pain from the lump. Please respond with additional questions and concerns if you wish.

is it treatable would you think? i don’t want her to be in pain, the lump is now probably a little bigger than a 5p coin now.

Yes, but it would entail surgery as these don't respond to conservative (medical) care. Please continue in this conversation if you wish.
