I noticed a large lump on my female dogs chest, she is about

Resolved Question:

I noticed a large lump on my female dog's chest, she is about 7 years old. It is right under here left front leg in the breast area. it is rather large but seems to be moveable and not too hard. I am worried what this might be, i just noticed it last night, its pretty big im sure i would have noticed it sooner so it must be new.

Hi Jacustomer-vrbdo81a~


The lump is something that could have many causes: inflamed lymph node, sebaceous cyst, lipoma. Because of her age and the description you gave me of what it feels like, I'm suspecting it's a lipoma or a sebaceous cyst, but I'm just guessing.


Here's more reading on lipomas and other cancers:

On lymph nodes:


The only way to positively identify what sort of lump or bump your dog has is, unfortunately, also through a trip to the vet. A fine needle biopsy (where the vet inserts a needle into one of the bumps and tries to aspirate/pull out material to look at under the microscope) will tell the vet, without question, what sort of problem your dog is having.


I hope this helps.
