@BDawg1005:
I thought Lexi has an almond shaped lump– I felt stupid when my hubby pointed out that it was her microchip!! Duh. Miles, however, actually has three lumps-- one is under his arm pit. We were told by Banfield that we should do surgery and then have them biopsied, but we are going to get a second opinion because they feel like fatty cysts to me and I would think the protocol would not be operate first... instead aspirate, send specimens to a lab, and then determine if they're benign...
Regarding the armpit lumps, and fatty cysts: Querk had a few of these, and yes, our vet felt them, said the felt like "not tumors" but then she aspirated them. She said all are benign, but we could remove them next time he was under, which is what we did. I definitely wouldn't jump to surgery.
