Breast Cancer in Pets. (yes, they get it too!!)
Many
pet parents don't realize that pets can also suffer from breast cancer.
In veterinary medicine, these tumors are referred to as
mammary gland tumors, and are unfortunately one of the most common kinds of cancer in pets.
Cats
generally have eight mammary glands, arranged in four pairs. Dogs
usually have 10 glands arranged in five pairs, though the number varies
with the size of the dog. Mammary gland tumors in dogs and cats can be
benign or malignant. In cats, around 90% of mammary gland tumors are
malignant. In dogs, approximately 50% are malignant.
How can mammary gland tumors be prevented in dogs and cats?
The
most effective way to prevent mammary gland tumors is to have your pet
spayed before she ever goes into heat. There is a myth that animals
should have one heat cycle (or give birth to one litter) before they are
spayed. In fact, dogs who are spayed
before their first heat
cycle are 2,000 times less likely to develop breast cancer! Cats spayed
before their first heat are 91% less likely to develop breast cancer
than unspayed cats. After just one heat cycle, the risk rises in both
dogs and cats.
Detecting mammary gland tumors
Just
like in people, performing mammary exams in dogs and cats is very
important. Early detection is key. If your dog or cat allows, perform a
mammary exam on her once a month. Gently feel the tissue under and
around each nipple, "rolling" the tissue between your fingers. Very
small mammary tumors often feel like a little BB pellet under the skin.
If you feel even a tiny lump or firm area, bring your pet to the
veterinarian immediately.
There is evidence that canine mammary tumors can become malignant over time, so prompt removal is essential.
Treatment of mammary gland tumors in pets
The
main treatment at this time is surgical removal. Depending on the
situation, your pet may need to have the affected mammary gland, several
mammary glands, or all the glands on that side of her body removed. The
tumor that is removed will be sent to the lab for a biopsy to tell you
if it is benign or malignant. If the tumor is malignant, your
veterinarian may refer you to a veterinary oncologist for consultation.
