Dog has baseball size lump on shoulder

I am sorry to hear about this lump. It is definitely large enough, that testing needs to be done.

If the vet is uncertain of what it could be, they will likely start with a simple fine needle aspirate test.

Fine-needle aspirate test is performed usually without anesthesia and is very quick. Your veterinarian takes a few needle samples from the lump (the needle is no larger than the needle used to give vaccines). The sample is smeared on to microscope slides and submitted to the laboratory. It is not always as definitive as a biopsy (this is a full tissue sample), but often it can yield enough information to help guide you and your vet as to whether a biopsy is needed, or if surgery should be performed.

This test is important because if it's a benign growth, cyst, reactive skin condition, it could be easily removed around its periphery. However, if its cancerous, the vet will need to take wider and deeper margins to help get the whole thing removed.

So, whether a needle test or biopsy needs to be done will be quickly determined after that vet visit.

Good Luck!
