My rat has a tumor-like lump. Does she need a vet if she seems fine?

about 12 hours ago i noticed a lump about the size of a walnut on the side of my two year old rat, I'm pretty sure it's a tumor as it's under the skin. it hasn't noticeably effected her in any way and I don't have much money to take her to the vet as I'm only 16 but I'm wondering if she'll be okay without treatment if she still living her life as normal or if I need to take her to a vet to get checked out.

Hi there. Sorry to hear that Rosie is having this issue. Any lump on your pet should be checked by a vet . I can tell you that rats get a lot of tumors so I am assuming it is a tumor. She is at the top of her lifespan already at 2 years old. They don't typically live longer than that. Here is a link to an article about tumors in rats: http://www.petmd.com/exotic/conditions/cancer/c_ex_rt_cancers_tumors# I hope this helps. If you can, get her to a vet for an exam. Best wishes to you and Rosie!
