sudden lump

Question
Hi, I have a male guinea pig which I resqued from the pound about three years ago. I'm guessing him to be around 6 or 7. He is very spunky, is eating well, and seems to be normal in every way. I pet him all the time, however, a large lump seems to have grown under his throat. It is not part of the skin, being that it can be moved around easily under the skin. I know I should take him to the vet, but I was wondering if you had any ideas before I did so, and if you know what the cost might be to have him treated. Thanks so much for any advice!

Answer
Hi,

So sorry for just now getting back to you. Been working overtime at work this last week.

It sounds like either a harmless fatty tumor or a lymphatic tumor. As in humans, lumps under the chin, behind the legs or in the groin area are always worrisome. A vet will have to do a needle aspiration on the lumps to find out if they are malignant or benign. Benign tumors can usually be left alone unless they are getting larger.

I don't know how much it would cost I am afraid it varies from vet to vet and such. Best way to find out how much it'll cost is by call up the vet office and describing the problem to them and then ask how much it'll cost. He'll for sure need to see a vet though.

I hope this helps,
 Take care,
