Dog’s Lump May Be Cancerous

Any lump that appears to contain a lot of cells could potentially be a tumor, either benign or malignant.

Q. My dog has a lump on her chest and our vet aspirated it yesterday and found a lot of cells. She said it should be removed as soon as possible. Since she found a lot of cells does that mean it’s a cancerous tumor?

A. Lumps on dogs can be many things: tumors, abscesses (infection), hematomas (blood), cysts (fluid) or granulomas (scar tissue from an old abscess). For this reason, they all should be checked out with a simple aspiration procedure and the contents looked at under a microscope.

Any lump that appears to contain a lot of cells could potentially be a tumor, and tumors are either benign or malignant. Other than in the case of a lipoma (which are fat cells), any tumor is potentially cancerous. For this reason, the lump on your dog should be removed and submitted for biopsy.

Biopsy will give you a definitive answer as to what the lump is, and to make sure it was removed in its entirety, or indicate if more testing is needed to check for any spread.

Why do lab dogs like to lick face so
much?

Why do lab dogs eat things that are
possibly
dangerous or harmful to their health (i.e.
junk,
mushrooms, wild berrys or rock salt)?
