Canine Cancer: What Are the Most Common Types of It?

Dogs of all ages are prone to developing cancer, but the elderly are particularly in jeopardy. Cancer is the most significant reason for mortality in pets older than middle age, affecting one in four dogs at some point during their lives. Some canine cancers are much more prevalent than others, just as in humans. Several dogs diagnosed with cancer can be saved by modern medical techniques.

Prevalent Types of Cancer in Dogs

When cells in the body increase without control, it is called cancer. Usually, cell division follows strict rules. A tumor can develop when a single cell develops a cascade of mutations that results in uncontrolled cell proliferation. It’s necessary to look out for problems in your dog, such as a lump or bump, a wound that won’t heal, puffy or swollen lymph nodes, lameness or inflammation in the bone, or uncommon bleeding.

Early on, or even often, there may be a couple of, if any, warning signs. If you find any of these signs or your dog “just isn’t fairly right,” do not wait to talk to a reputable vet. Not all dog cancers are included here, but a few of the most common ones are.


Like mast cell tumors, melanoma tumors can develop on dogs’ skin. Many melanoma tumors are nonmalignant and straightforward to cure; however, malignant melanoma is even more severe. Regretfully, malignant melanoma in dogs can rapidly metastasize or spread to other body parts. These tumors frequently have black pigmentation, yet they can additionally be colorless.

Dogs with melanoma commonly have it on their feet or in the spot surrounding their lips. Suppose you saw a dark red bump on your dog’s skin. If so, you need to get your dog to a pet hospital that offers veterinary oncology services immediately so they can begin treating it and stop the cancer from spreading. Moreover, you can visit the website of an animal hospital to learn more info about vet oncology.

Liver Cancer

Often there are no outwardly noticeable clinical indications of liver cancer in dogs, making it a particularly deadly illness. This malignancy can be brought on by various malignant tumors, the most common of which is hepatocellular carcinoma. Usually, this type of tumor stays contained in the liver and does not spread.

Although older dogs are more likely to obtain liver cancer, it can affect dogs of any breed at any age. Due to their progressive decrease in health, senior dogs need extra care and focus. Regular visits to a geriatric vet are the most excellent technique to guarantee their continued health and safety from possibly fatal conditions.


Several types of canine bone cancer exist, but osteosarcoma is the most constant. After adulthood, large-breed dogs, including poodles, are at high risk of developing bone tumors. This malignancy has the potential to spread rapidly and cause prevalent disease. Numerous potential damaging results exist, but the most disconcerting is an abrupt onset of lameness.

If this happens, take your dog to the nearest vet diagnostic laboratory for an X-ray or MRI.

The Takeaway

Watch for any uncommon behavior or changes in your dog’s look. Some changes in the body that could show cancer develop gradually and are not always recognizable in the beginning. A favorable outcome is far more likely when it is uncovered early. Checking for cancer at regular health visits with a vet is a must. However, you might be more proactive about your dog’s health by regularly looking for warning signals. When unsure, see a veterinarian.
