Top 10 Signs of Cancer in Dogs
Article by Christine McLaughlin | DogTime
What Is Cancer?
But first it’s important to define cancer. Cancer is a disease where cells grow out of control, invade surrounding tissue, and can spread (metastasize). Just like in humans, cancer can take many forms in dogs. The disease can be localized (in one area) or generalized (spread throughout the body). Cancer is considered multifactorial, which means it has no known single cause but heredity and the environment are thought to be factors.
According to the American Kennel Club’s Canine Health Foundation, the most common types of canine cancer include:
Mast Cell Tumors
Transitional Cell Carcinoma
Catch It Early
While canine cancer can be treated (with varying success) using surgery, chemotherapy, radiation, and immunotherapy, the best thing you can do is to catch the disease in its early stages — before it spreads. Early detection is critical for successful treatment and recovery.
One of the most common ways dog owners detect cancer is by finding a lump or a mass on their dog (the dog typically isn’t bothered by the lump). But it’s important to clarify, just because you find a lump, doesn’t mean it’s cancer. Still, a veterinarian should investigate any lump as soon as possible.
Symptoms to Detect
The National Canine Cancer Foundation says there are 10 warning signs your dog might have cancer:
- Abnormal swellings that persist or continue to grow
- Sores that don’t heal
- Weight loss
- Loss of appetite
- Bleeding or discharge from any body opening
- Offensive odor
- Difficulty eating or swallowing
- Hesitation to exercise or loss of stamina
- Persistent lameness or stiffness
- Difficulty breathing, urinating, or defecating.
If you find a lump or your dog has any of the other symptoms above, don’t delay in getting it investigated by your family veterinarian. If it’s confirmed your dog has cancer, it’s advised to get a second opinion — possibly by a board-certified veterinary oncologist — to discuss your options.
Some cancers can be cured with one or a combination of treatments, but sadly, many cannot and merely delay the inevitable. Some pet owners opt out of treatment completely and instead help their dogs with pain management (palliative care) throughout the course of the disease.
While not all cancers can be prevented, certain steps pet owners can take to help their dogs have a lower risk of developing it. For example, having your dog spayed or neutered at a young age can help prevent reproductive cancers. Some veterinary experts encourage giving your dog antioxidants in supplement form like vitamins A, C, E, beta carotene, lycopene, and the mineral selenium to help ward off cancer. Healthy nutrition and exercise are also believed to help prevent cancer from developing.
The bottom line: Awareness of cancer symptoms and quick action are key to giving your dog the best chance for survival.
