Basal Cell Tumor

What are Basal Cell Tumors?
One of the most common skin tumors in pets, basal cell tumors arise from the epithelial cells, which are the cells that make up most  of the top layer of skin (the epidermis). They are most commonly seen in medium middle age to older dogs. Basal cell tumors  are usually benign, although about 10% are malignant.

How does my dog get Basal Cell Tumors?
In humans, basal cell tumors are often associated with sun exposure, but this has not been demonstrated in dogs or cats. At present, the cause is unknown but there may be a genetic component.

How do I know if my dog has Basal Cell Tumors?
Suspect any raised  hairless mass with well-defined borders, especially if they are located on the head, neck or shoulders. In cats, they may be darkened and may be ulcerated. Your veterinarian will perform a fine needle aspirate in which a cell sample is drawn up into a syringe.  If that's not definitive, a tissue sample may be needed.

What can I do about Basal Cell Tumors?
The most effective treatment is to surgically remove the mass. This will usually cure the condition. Very small masses may be taken off with cryosurgery.

Is there anything I can do to prevent my dog from getting Basal Cell Tumors?
Although not proven, it may be a good idea to avoid letting your pet, especially if light pigmented, sun bathe.

Are there certain breeds that get more often?
Cocker Spaniels and Poodles are more commonly affected.
