Signs of Pet Cancer


Pet cancer affects both dogs and cats, but often in a different way. Because animals now live longer than ever before, approximately 50 percent of dogs over age 10 will deal with some type of cancer. The most common types of canine cancer include malignant lymphoma, mast cell cancer, mammary gland tumors, bone cancer, and soft tissue sarcomas.

The signs of cancer in dogs are similar to what humans experience. The difference is, of course, that we have the ability to get our symptoms checked out while dogs depend on us to notice when something is wrong. That's why it's a good idea for all dog owners to be aware of the following problems that could indicate canine cancer:

• A new lump or bump

• A wound that scabs over but doesn't heal

• Abnormal bleeding

• Swollen lymph nodes

• Swollen legs or limping, which may indicate bone cancer


Feline Cancer

Cats develop cancer about half as often as dogs, but their tumors tend to grow much more aggressively. This is possibly due to feline cancer being diagnosed later due to the cat's natural tendency to hide illness from their owners. Some of the most common cat cancers include lymphoma, oral squamous carcinoma, and fibrosarcoma. These are cancers associated with the blood, skin, and connective tissues. Tumors do develop in other areas of a cat's body, but they are much more rare.


Typical cancer symptoms in cats include:

• A new lump or bump

• Frequent vomiting or diarrhea

• Difficulty breathing

• Refusal to eat and weight loss

• Lack of grooming, which is normally very important to cats


Give our Veterinarians a call to Look at Any New Symptom

These symptoms don't necessarily mean that a dog or cat has cancer, but they should always be checked out to identify underlying issues. This is especially important if the symptoms come on suddenly and the animal appears lethargic for no apparent reason.  By catching cancer early, you’ll be able to take advantage of early treatment options, and provide your pet the best opportunities for recovery.
