Signs of Cancer in Pets from a Veterinarian's Perspective


As a pet owner, it's natural to want to do everything you can to keep your furry friend healthy and happy. One of the best ways to do that is to be aware of the signs and symptoms of cancer—the sooner you catch it, the better. Here are a few things to look for.

Lumps and Bumps

One of the most common—and easily noticeable—signs of cancer in pets is the presence of lumps and bumps under the skin. These can appear anywhere on the body, but they're often found on the chest, abdomen, or legs. If you notice any lumps or bumps on your pet, make an appointment with your veterinarian right away so they can determine if they're benign or something more serious. 

Weight Loss

Cancer can also cause weight loss, even if your pet is eating the same amount as usual. This is usually due to cancer cells stealing nutrients from healthy cells, which results in weight loss and muscle wasting. If you notice your pet losing weight unexpectedly, don't hesitate to bring them to Happy Valley Pet Hospital.

Lethargy and Loss of Appetite

Similar to weight loss, cancer can also cause lethargy and a loss of appetite. This is again due to cancer cells taking nutrients away from healthy cells, leaving your pet feeling tired and weak. If you notice your pet becoming more sluggish than usual or not eating as much as they used to, it's time for a trip to the vet. 

Changes in Bathroom Habits

Last but not least, changes in bathroom habits can also be indicative of cancer. This could manifest as either increased urination or defecation (usually with blood present) or a decrease in urination or defecation altogether. If you notice any changes in your pet's bathroom habits, don't wait to have them checked out by a professional. 

Treatment Options 

While a diagnosis of cancer may sound scary at first, there's no need to panic. There have been major advances in veterinary oncology in recent years, which means there are now more treatment options available than ever before. The type of treatment your pet will receive will depend on the type and stage of their cancer, so be sure to discuss all of your options with your vet before making a decision. In many cases, pets with cancer can go on to lead happy and healthy lives for years after diagnosis. 


Many people don't realize that cancer is just as common in pets as it is in humans. The good news is that there are now more treatment options available than ever before—so if you notice any changes in your pet's behavior or appearance, contact us right away!
