About a month ago I felt a pretty small lump near my 2 year old cats nipple, I was worried about it for a day or 2 but I eventually totally forgot about it until a few hours ago when I was petting her and I felt a tiny lump near her nipple again. It feels like a pimple and I'm very worried it could be cancer because she isn't spayed yet. I'm also very anxious because I know I have to take her to the vet asap but my vet charges $160 just for looking at her without even touching her, I can't imagine how much it'd be for blood tests and stuff. I just don't have that much money for the vet at the moment. Its only 1 nipple and it feels like there is a pimple right under it. I feel like its decreased in size but it worries me that it hasn't gone away.
