10 WARNING SIGNS OF CANCER IN DOGS & CATS
If cancer is detected early it can be treated more effectively, so it’s important to check your dogs & cats regularly for the 10 Early Warning Signs as recommended by the Veterinary Cancer Society.
If your dog or cat has any of these early warning signs of cancer, you should take him or her to your veterinarian as soon as possible for a more complete examination. In addition, you should keep your pet away from environmental toxins like lawn fertilizers and surface and rug cleaners that have warning labels relative to children and pets. Many veterinarians see a link between environmental toxins and cancer.
1. Swollen lymph nodes
These glands are located throughout the body, but are most easily detected behind the jaw or behind the knee. When these lymph nodes are enlarged they can suggest a common form of cancer called lymphoma. A biopsy or cytology of these enlarged lymph nodes can aid in the diagnosis.
3. Abdominal distension
When the stomach or belly becomes rapidly enlarged, this may suggest a mass or tumor in the abdomen, or it may indicate some bleeding that is occurring in this area. A radiograph or an ultrasound of the abdomen can be very useful.
4. Chronic weight loss
When a pet is losing weight and you have not put your pet on a diet, you should have your pet checked. This sign is not diagnostic for cancer, but can indicate that something is wrong.
5. Chronic vomiting or diarrhea
Unexplained vomiting or diarrhea should prompt further investigation. Often tumors of the gastrointestinal tract can cause chronic vomiting and/or diarrhea. Radiographs, ultrasound examinations and endoscopy are useful diagnostic tools when this occurs.
6. Oral odor
Oral tumors do occur in pets and can cause a pet to change its food preference (i.e. from hard to soft foods) or cause a pet to change the manner in which they chew their food. Many times a foul odor can be detected in pets with oral tumors. A thorough oral examination with radiographs or CT scan, necessitating sedation, is often necessary to determine the cause of the problem.
7. Unexplained bleeding
Although bleeding disorders do occur in pets, they usually are discovered while pets are young. If unexplained bleeding starts when a pet is old, a thorough search should be undertaken.
A dry, non-productive cough in an older pet should prompt chest radiographs to be taken. This type of cough is the most common sign of lung cancer. Please remember there are many causes of cough in dogs and cats.
10. Straining to urinate
Straining to urinate and blood in the urine usually indicate a common urinary tract infection; if the straining and bleeding are not rapidly controlled with antibiotics or are recurrent, cancer of the bladder may be the underlying cause. Cystoscopy or other techniques that allow a veterinarian to take a biopsy of the bladder are useful and sometimes necessary to establish a definitive diagnosis in these cases.
