What Are the Different Types of Dog Tumors?

A team of vets understands how upsetting it can be when you discover your dog is suffering from cancer, as dogs are cherished parts of our family and often our closest pals. While most people don’t want to consider that their dog might be in a state of illness, knowing the kinds of cancers found in dogs could help you catch the disease early when treatment is most effective.

Certain canine tumor types can be treated. Most often, they are locally invasive tumors that may be removed surgically. Unfortunately, there is typically no cure for cancers that are spread to other parts within your dog’s anatomy or metastasize.

Getting the most information you can learn that your pet has cancer before making any decisions is crucial. A consultation with a veterinary specialist can help you understand the possibilities of the results and what to expect for your pet. They will discuss the various treatment and what they will mean to your pet’s longevity and quality of life.

Dog Tumor Types

In comparison to human cancers, canine tumors are handled differently. It is essential to consult your vet to understand the specific characteristics of each type of cancer in dogs because other types of cancer are graded differently.

Mast Cell

Mast cells are cancerous tumors that develop in the dog’s skin’s mast cells. Immune system cells are typical mast cells. They trigger allergic reactions like hives or insect stings.

Mast cell tumors may have diverse appearances, including simple cysts or zits. They are also capable of mimicking benign tumors such as lipomas.


Lymphocytes, white blood cells, give birth to the malignant form of cancer called lymphoma. An essential component of the dog’s immune system is the normal lymphocyte.

Large, complex lymph nodes, typically found within the jaw area and between the shoulders or near the back of the knees, are a classic indicator of lymphoma. Lack of appetite or desire to eat is also a symptom. Look up “Animal clinic in Grants Pass” for the best results.


The fat cells can lead to benign tumors, known as lipomas. They usually occur in the fatty layer immediately under a dog’s skin or in subcutaneous fat.

Lipomas are very common and can be pretty massive. They generally affect the appearance (pet parents may not like the lumpy, bumpy appearance a pup appears). However, they may create issues when they’re placed in the wrong place. Liposarcoma is used to describe the malignant tumor’s less common variant. Consult your veterinarian for any veterinary dental care information you might need.


One form of cancer that arises from bone cells is known as osteosarcoma. Osteosarcomas cause swelling in the limbs, bone fractures, and lameness. They can be painful.

Large dog breeds including Boxers, Golden Retrievers, German Shepherds, Great Danes, Great Pyrenees, Greyhounds, Labrador Retrievers, and Rottweilers are often affected by osteosarcoma.


The benign tumors arise from histiocytes on the skin. Histiocytes are an immune system cell type that assists in the defense against infection. In weeks, they tend to decrease and then disappear by themselves.

The condition is prevalent in puppies. Histiocytoma can be frequent in puppies. The most frequent are those of Labrador Retrievers, Boxers, Shar Peis, Bulldogs, American Pit Bull Terriers, Staffordshire Terriers, and Scottish Terriers.


The benign tumors referred to as papillomas or warts are brought on through the canine papillomavirus. The infection is spread by touch. It is most often seen on the tongue, lips, throat, or gums; however, it can occur in different places and is more common in dogs who play in dog playgroups, parks, or daycares.

Since this is a species-specific virus and is not a threat to you or any other animal living at home could contract it. Papillomas typically disappear by themselves within several weeks. Read on this link for more details.
