10 Pet Cancer Warning Signs

Of all dog diseases, cancer is the leading cause of illness and death in middle-aged and older dogs. 50% of canines over 10 years old die from some form of cancer, whether it’s dog skin cancer, bone, lymph or other types of the disease. 33% of felines also fall prey to cat skin cancer and feline leukemia, among other cancers.

As with humans, any cells in your pet's body can be affected, including skin, bone, muscle, liver, lung, spleen, intestinal tract, and nervous system cells. Aging itself makes bodies more vulnerable to cellular changes that can challenge immunity and lead to cancer, but advancements in pet nutrition, vaccinations, routine veterinarian checkups and parasite prevention can help our pets live longer.

Looking for early warning signs is a great way to help prevent or treat pet cancer because it enables you to catch it as soon as possible. And, thanks to all of the advancements in treatments and care, pet cancer is no longer a death sentence.

 

 

What Are the Early Warning Signs of Pet Cancer?

Pet cancer is understandably a major concern for pet parents. The earlier the cancer is detected, the quicker it can be treated, so watch for these signs and symptoms in your dog or cat. See Dr. Gerald S. Post’s Video.

Enlarging or Changing Lumps

Pet parents should first check for lumps on their pet and over time note if there’s any change in size, shape or consistency. A lump that grows rapidly or changes its texture or shape should be evaluated. Biopsies, abdominal ultrasounds, x-rays and screening tests can help the veterinarian and oncologist determine whether the lump is cancerous or benign.

Swollen Lymph Nodes

Lymph nodes are located throughout your pet’s body, but the ones behind the jaw or knees are the easiest to check. Enlarged lymph nodes may indicate a common form of cancer known as lymphoma. A biopsy or cytology of any enlarged nodes can help determine the diagnosis. 

Abdominal Distension

If your pet’s belly or stomach area rapidly enlarges, it could indicate a mass, tumor or internal abdominal bleeding. Abdominal radiographs or ultrasounds can help determine the cause.

Chronic Weight Loss

If your dog or cat loses weight without a change in diet, schedule an appointment with your veterinarian. Weight loss is not a diagnostic sign of cancer, but it can indicate something is wrong.

Chronic Vomiting or Diarrhea

If your pet has severe or persistent vomiting or diarrhea, see your veterinarian as soon as possible. Gastrointestinal tract tumors can cause chronic vomiting and/or diarrhea, so radiographs, ultrasound examinations and endoscopy are all useful tools to rule out cancer.

Bleeding from the mouth, gums or any of your pet’s orifices that’s not related to physical trauma should be checked. Bleeding disorders can occur in dogs and cats, but if a pet has unexplained bleeding, your veterinarian should do a thorough examination.

                • Cough

Chest radiographs may be indicated.

                  • Lameness
                  • Unexplained lameness is a common sign of bone cancer, especially in large or giant breed dogs. Radiographs of the affected area can help detect this type of cancer. 
                  • Straining to Urinate

Straining to urinate and blood in the urine usually indicate common urinary tract infections or inflammatory disease. If these symptoms aren’t quickly controlled with antibiotics or reoccur frequently, bladder cancer may be a possibility. Veterinarians can biopsy your pet’s bladder to establish a diagnosis.

Oral Odor

If your dog or cat seems to be chewing differently, or changes preference from hard food to soft, it could be an oral tumor. Another sign is foul breath. Your veterinarian can do a thorough oral examination with radiographs.
