Cancer in Dogs and Other Pets

According to the Pet Cancer Awareness organization, cancer is the No. 1 disease-related cause of death in cats and dogs - a fact only known to 20 percent of pet owners. The Pet Cancer Foundation reports occurrences of pet cancer are on the rise, as nearly 50 percent of deaths in pets more than 10 years old are caused by cancer. Up until just a few years ago, a pet diagnosed with cancer was afforded few options. But recent advancements in treatment and technology are offering better chances of survival for these furry companions. Most of the treatments come at a high price, though, and many families cannot afford the necessary treatments.

Contributing Factors in Pet Cancer

Callous and improper breeding practices have caused certain breeds to become genetically prone to cancer. Some of these breeds include: golden retrievers, Labrador retrievers, Rottweilers, Bernese mountain dogs, and boxers. When looking to adopt a pet, it is very important to question breeders on the occurrence of cancer in the blood line. Additionally, it is best to avoid animals that have been "mass" bred in puppy and kitten farms.

Another human-induced health concern for pets is over-vaccination. Though it may be necessary to vaccinate kittens and puppies, annual vaccinations are not necessary, and some vaccinations may not be required at all (depending on the geographic occurrence of various diseases). Despite how profitable vaccinations may be for veterinarians and the chemical companies producing the inoculations, it has been clinically proven that over-vaccinations weaken the immune system, causing susceptibility to cancer.

Environmental toxins also contribute to cancer among pets. Countless pets are exposed to chemicals in the environment, such as asbestos, 2,4-D acid, and petroleum derivatives found in carpet and herbicides. Even chemicals in pet foods have shown to be an issue, as research has confirmed daily doses of the chemical additives and preservatives found in pet food can build up in the body and lead to the development of cancerous cells.

Symptoms to Watch For

Formed in 1977, the Veterinary Cancer Society offers 10 early warning signs for pet owners to be aware of and watch out for:

1. Abnormal swelling that persists or increases in size
2. Sores that do not heal
3. Weight loss
4. Loss of appetite
5. Bleeding or discharge from any body opening
6. Disturbing odor
7. Problems with eating or swallowing
8. Hesitation to exercise or loss of stamina
9. Persistent lameness or stiffness
10. Difficulty breathing, urinating, or defecating

If your pet exhibits any or a combination of these warning signs, you are advised to see a veterinarian for a full assessment. Make sure to keep your pets away from known environmental toxins, such as asbestos-containing materials, lawn and garden fertilizers, and surface and rug cleaners.
