It is fast-growing and quick to metastasize or spread to other parts of the body.

It is not exactly known how these tumors develop but genetics is suspected to play a role.

Mast Cell Tumours

The most common of dog skin cancers.

It is not yet known why mast cell tumors occur but again genetics is likely to suspect.

Forming in the mast cells of the body’s immune system, it is speculated by veterinarians that hormones, like estrogen, and progesterone also play a role in speed of tumor growth.

Squamous Cell Carcinoma – Dog Skin Cancer.

Caused by sun damage, these tumors can be aggressive and spread through lymph nodes in the body.
