Cancer is a word no pet parent wants to hear. Yet, it’s a reality that many dog and cat owners face each and every year. Sadly, cancer remains one of the leading causes of death among pets. Gaining a better understanding of its prevalence, the breeds most affected, and the importance of early detection can make a significant difference in treatment outcomes and quality of life.   

How Common Is Cancer in Pets?   

Dogs: Statistically, cancer affects approximately 1 in 4 dogs at some point in their lives. For dogs over the age of 10, the incidence increases dramatically, with almost 50% of them developing some form of cancer. According to the American Veterinary Medical Association (AVMA), cancer is the leading cause of death in older dogs.   

Cats: Cats are less commonly diagnosed with cancer than dogs but, when they are, the disease is often more aggressive. An estimated 1 in 5 cats will develop cancer in their lifetime. Feline cancers can be harder to detect in early stages due to the stoic nature of cats and their tendency to hide symptoms.   

Breeds Most Prone to Cancer   

Certain pet breeds have shown to be statistically more genetically predisposed to higher cancer rates. Here are some of the breeds with increased risk:   

Dog Breeds:   

  • Golden Retrievers: High rates of lymphoma and hemangiosarcoma.
  • Boxers: Prone to mast cell tumors.
  • Bernese Mountain Dogs: Increased incidence of histiocytic sarcoma.
  • Rottweilers: Commonly develop bone cancer (osteosarcoma).
  • Scottish Terriers: Higher risk for transitional cell carcinoma (a type of bladder cancer).
  • Great Danes and Greyhounds: More susceptible to osteosarcoma.

While cancer is less breed-specific in cats, some breeds show higher incidences:   

Cat Breeds:   

  • Siamese Cats: More prone to mammary tumors and intestinal cancer.
  • Persians and Himalayans: Have a higher risk of lymphoma and skin tumors.
  • Mixed-breed cats with outdoor exposure are more likely to develop squamous cell carcinoma, especially on sun-exposed areas like ears and noses.

Why Early Detection Matters   

The key to improving treatment outcomes in pets with cancer lies in early detection. Catching cancer in its early stages often allows for more treatment options, less aggressive therapies, and a better prognosis.   

As May is Pet Cancer Awareness Month, we are using his time to introduce our clients and patients to our new Pet Cancer Risk Assessment Test. This test looks at key health markers to develop a personalized risk assessment of your pet’s likelihood of developing cancer within the next 6 to 12 months. A score range between 0 and 10 will be provided to indicate the health status and risk of your pet for cancer.   

We are recommending this test for all dogs and cats over the age 5, as well as for those breeds that fall in the high-risk breeds listed above. By incorporating this test into our regular protocol, screening will help us not only with early detection, but to establish a baseline, monitor changes, and introduce treatments and therapies to lower the likelihood of disease in your pet’s body. The test will measure inflammation and nutrient levels, and is meant to identify if your pet's body if your pet's body has created an environment that promotes cancer development.   

From now until June 30, 2025 new and existing patients can get a wellness exam and our Pet Cancer Risk Assessment Test for just $249. Clients who have been in with their pets for their annual or biannual exams within the past 12 months can do just the Pet Cancer Risk Assessment Test alone.   

Call our office at (973) 606-1101 to learn more and to schedule your exam and test. Cancer is a challenging diagnosis but understanding the risks and being proactive can make a world of difference. For high-risk breeds, regular screenings and close monitoring are essential. Whether you have a senior Golden Retriever or a young Siamese cat, staying informed and vigilant gives your pet the best chance at a healthy, happy life.
