Almost everyone has been affected by cancer. Either personally, a loved one, a friend, or co-worker.
Unfortunately, cancer affects our furry friends as well.
Approximately 1 in 4 dogs will develop cancer at some point in their lifetime. The number increases to almost half of dogs over 10 years of age will develop cancer.
Similarly to humans, identifying cancer earlier can in some cases lead to a better outcome. Because of this, the owner should play an active role in monitoring their beloved pet.
It can be as simple as feeling for lumps and bumps while petting them and observing what is normal for their dog or cat, so when there is a change, they can consult with their primary veterinarian.
Other things to look for - Does the pet's abdomen look distended? Are they having a harder time urinating or defecating? Vomiting? Are they having a harder time eating or is there blood-tinged saliva? Are they coughing? Are they limping? Have they suddenly lost weight?
Having a partnership with a veterinarian throughout the animal's life is crucial for preventing disease, as well as for earlier detection of problems that initially can be subtle.
A physical examination when annual vaccines are due allows the veterinarian to check the mouth, lymph nodes, listen to the heart/lungs, feel the abdomen for abnormalities, and monitor for changes in body weight. As the animal ages, additional diagnostics, such as blood work can be added. Having baseline blood work before they get sick can be very helpful.
Recommendations from your veterinarian can also be influenced by the breed of dog as some breeds of dog are more likely to develop certain types of cancer. In those breeds, more frequent and additional testing can be done.
Additional testing can be radiographs (x-rays), abdominal ultrasound, aspiration/biopsies of suspicious areas, and advanced imaging (CT scan).
A recent study in the Journal of Veterinary Internal Medicine (2024 Jul-Aug;38(4):20892098) looked at a large group of cats which were deemed "healthy" by their owner. Within 2 years, 28% of mature adult cats (ages 7-10) and 58% of older cats (> 10 years of age) that were confirmed healthy at inclusion developed new diseases, most commonly early kidney disease, hyperthyroidism, chronic gastrointestinal disease, liver disease or pancreatitis, and cancer in 7%.
Did you catch that? Over half of cats over the age of 10 years had developed a medical condition.
So now what? If you have any concerns regarding your pets health, contact your regular veterinarian and discuss it with them.
If appropriate, your veterinarian can refer to specialists for additional diagnostics.
If your pet has been diagnosed with cancer, consultation with board certified specialists for treatment recommendations may be needed. Information regarding staging, treatment options (chemotherapy, surgery, radiation), and prognosis can be discussed and an informed decision can be made.
