So sorry she is having these problems. Drinking and urinating more can be a sign of kidney disease, Cushing's disease, diabetes, Addison's disease, infections, thyroid disease, etc. The only way to know the cause is to have a vet run some bloodwork and a urinalysis. The lump could be a cyst, infection, benign or cancerous mass. A needle aspirate or biopsy may be necessary to diagnose. She really needs to be examined by a vet. Try to find a low cost clinic in your area or a vet that would take a payment plan. You could also apply for Care Credit which is a veterinary credit care. Hope you can find her the help that she needs.
