Answer
She needs a vet, but ONLY a vet that knows what they are doing when it comes to rats. They are not easy to find.  Let me know your location and I will help you find a vet that is qualified to see rats.  This lump can be easily removed.  It is a mammary tumor and this is common in rats her age.  Read sandyscrittercity.com and refer to the page on tumors for all the info you need on them.
