Canine cancer: the warning signs and the way to a cure?

According to the Animal Cancer Foundation, one in four dogs will develop cancer in their lifetime.  That’s a pretty scary statistic.  A diagnosis of a malignant cancer for one’s dog is just as traumatic and worrying as a diagnosis of the disease in any member of the family.

Experts in both human and canine cancers agree that we still have much to learn about the types of these diseases and how to treat them.

The National Veterinary Cancer Registry has been launched recently to identify and register pets diagnosed with cancer.  The Registry’s goal is to facilitate and promote medical treatments that lead to advances, higher success rates and eventual cures for cancer in pets and people by matching animals with cancer to clinical trials for new cancer treatments.

The Registry is a joint venture between the CARE Foundation, Baylor University Medical Center (BUMC) at Dallas and the Texas Veterinary Oncology Group.

Dr Gerald S Post, Founder and President of the Animal Cancer Foundation says there are 10 warning signs of cancer in both dogs and cats.  They are:

1. Swollen lymph nodes: These “glands” are located all 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.

2. An enlarging or changing lump: Any lump on a pet that is rapidly growing or changing in texture or shape should have a biopsy. Lumps belong in biopsy jars, not on pets.

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. Many cancer patients have weight loss.

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. Unexplained bleeding: Bleeding from the mouth, nose, penis, vagina or gums that is not due to trauma should be examined. 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.

7. Cough: 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.

8. Lameness: Unexplained lameness especially in large or giant breed dogs is a very common sign of bone cancer. Radiographs of the affected area are useful for detecting cancer of the bone.

9. 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.

10. 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 it chews its 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.

  1. This is a great initiative. Chronic weight loss is an especially good indicator.
