good to ask the vet about lumps. i've had 25-30 lumps and a lot of them needle biopsied like Mr. Mikey says. most were sebaceous cysts and benign. one was a cancer and was fortunately thoroughly removed we think. i had to get another surgeree recently for suspicious lumps, and it came back as the benign version of my cancerous lump (different location). I am a 12 year old basset. i'm still kicking and my face is all white. Worm.
