Lumps & Bumps – Dogs & Skin Cancer

Finding a Lump on Your Dog

If you have found a lump or discolored patch of skin on your dog you’re bound to begin worrying about cancer. That said, it’s important for pet parents to remember that not all lumps and bumps are cancerous, and for those that are cancerous many are treatable when detected early. If you have found something suspicious on your dog take your pup to the vet for a full examination as soon as possible. 

3 Types of Skin Cancer Seen in Dogs

Squamous Cell Carcinoma

Skin squamous cell carcinoma is the most commonly diagnosed form of skin cancer in dogs and typically seen in older animals. These tumors appear as raised wart-like patches or lumps that are firm to the touch and typically located on the dog’s head, lower legs, rear, and abdomen. Exposure to the sun may be a cause of squamous cell carcinoma, however, there could also be a link to papillomavirus. This form of cancer is frequently seen in white Bull Terriers, Dalmatians, Beagles, and Whippets.

Malignant Melanoma

Melanomas are raised bumps that are often (but not always) dark-pigmented and frequently found around the dog’s lips, mouth and nail bed. While most melanomas are benign they can be malignant. Malignant melanomas are a very serious threat to your dog’s health. These tumors grow quickly and have a high risk of spreading to other organs. Male dogs are more at risk of melanomas than females and certain breeds such as Schnauzers and Scottish Terriers also face an increased risk.

Mast Cell Tumors

Mast cell tumors are another type of cancer commonly diagnosed in our canine companions. This cancer occurs in the mast cells of the dog’s immune system. Mast cell tumors can grow anywhere on your pup’s skin, including internal organs however, some of the most common sites for mast cell tumors are on the limbs, lower abdomen, and chest.  This form of skin cancer is most often diagnosed in dogs between ages 8 -10 years old. Some of the breeds facing an increased risk of developing this disease include: Boxers, Pugs, Rhodesian Ridgebacks, and Boston Terriers.

Diagnosing Dog Skin Cancers

To diagnose skin cancer in dogs, your vet may perform a fine needle aspiration in order to take a small sample of the tumor’s cells to examine or perform a biopsy in order to take a portion of the tumor’s tissue for examination. These samples will be sent to a lab to be analyzed, in order for your vet to provide you with an accurate diagnosis of your dog’s condition. To determine the extent of cancer in the body after the initial diagnosis, additional diagnostic testing can help to optimize treatment recommendations and more accurately predict prognosis.

Treatment for Skin Cancers in Dogs

Often dogs that are diagnosed with skin cancers in the early stages can be treated successfully and go on to live full active lives.

Cancer can be treated with several different therapies or treatment combinations, including surgery, chemotherapy, immunotherapy, targeted therapies or palliative care when appropriate. When it comes to the prognosis and treatment for cancer in dogs, options will depend on a number of factors, such as the type of tumor, the tumor’s location, how advanced the cancer is.

Monitoring Your Dog’s Health

Spotting the signs of skin cancer while the disease is still in the early stages is the key to good treatment outcomes. Familiarizing yourself with all your dog’s lumps, bumps, and rashes, during your regular grooming routine, as well as visiting your vet for routine wellness exams can help to catch skin cancers in the early stages.

If you notice an unexplained or unusual lump or bump on your dog, or if you notice swelling around your dog’s toes consult your veterinarian as soon as possible. When it comes to your pet’s health it’s always better to err on the side of caution.
