Dog Nasosinal Cancer

Veterinarian Reviewed on March 29, 2014 by Dr. Janice Huntingford

Dog Nasosinal Cancer

Nasosinal is a big word for a small area of your dog’s body. The nasal cavity is a small space behind the nose that is filled with air. The sinuses in that area communicate with the paranasal sinuses. These are the connecting ones. There are several types of cancers that affect the region, most commonly carcinomas and some sarcomas. Although metastasis is low initially, but affects about half of the dogs at their death.

Nasosinal cavities are more common in larger breeds of dogs than in smaller breeds of dogs. In dogs, they are not very common but are often fatal.

Signs and Symptoms

Symptoms for nasosinal cancers are the same in both dogs. They include but are not limited to nasal discharge, eye discharge, nosebleeds, Dog Difficulty Breathing, Dog Weight Loss and facial deformities in the advanced stages. The deformity will occur as the disease progresses and bone mass is decreasing. Dog owners average about three months of symptoms before consulting with a veterinarian. If the bleeding or discharge is limited to one nostril, the probability of Dog Cancer is increased.


The primary method of diagnosing this type of tumor is one of the advanced imaging techniques such as MRI or CT scans. Both are very expensive. It will allow your veterinarian to locate the tumor and plan for treatment such as radiation, chemotherapy or surgery. Normal x-rays cannot give the detailed imaging that will distinguish the tumor from some inflammation in the nose.

The nose can also be vigorously flushed in an attempt to flush out particles of the tumor. Needle biopsies can also be performed on your dog. Either of these will be done with the aid of sedation or anesthesia. In the event that the surrounding lymph nodes are enlarged, biopsies should be done on the lymph nodes as well.

Pain in dogs with cancer

All cancers cause pain in dogs. This Dog Pain is not only caused by the cancer, but often by the treatment for these cancers. Surgery, radiation and chemo can cause an increase in pain. If the pain your dog is experiencing is not taken care of, your dog will drastically lose any quality of life. It is important to consult with a veterinarian who is experienced in oncology and familiar with the treatment of the associated pain. It is important to take care of pain before the causative procedure takes place. Your dog will be less hesitant to return to the clinic, if the experience is not extremely painful.

Home treatment

Along with pain management, maintaining nutritional status is also extremely important. Consulting with your vet as to high nutrition choices will assist your dog to maintain their energy status. By supplying your dog with the proper diet, you can prolong their life to some degree.


The prognosis for dogs with nasosinal tumors is not great. The average survival rate for dogs is about one year. For dogs, a combination of radiation and Dog Cancer Chemotherapy is more effective than either one alone. If the disease is allowed to progress without treatment, the prognosis becomes less favorable.
