ginea pig lump

Question
Hi, my name is Brian and my ginea pig, Frankie just turned 3 years old.  I noticed that he has a lump about the size of a pencil eraser just behind his right arm.  The lump is hard and doesn't seem to cause him pain.

Do you think this could be a fatty deposit or a tumor (I hope not)?  What advice can you give?  I appreciate your help.

Thanks,

Brian

Answer
Brian --

First, I apologise for the delay in my response.  AllExperts.com and my computer have been having some difficulties with communication.  :)  It should be fixed now, though, so any future inquiries should be responded to much more quickly.  I am sorry about the delay.

I think the lump could be either a fatty deposit or a tumor, as well as a couple of other possibilities, such as an abcess.  I would have this animal checked by a vet to ensure that he is healthy.  If the vet gives him the all-clear, and it doesn't seem to be causing him any pain, I wouldn't worry too much about the lump.

I hope this is helpful, and I apologise again for the delay in response.  Good luck!
