Nose Cancer (Adenocarcinoma) in Dogs


Nasal Adenocarcinoma in Dogs


Nose cancer (or nasal adenocarcinoma) occurs when too many cells in the animal's nasal and sinus passages come together. The disease progresses slowly and occurs both in dogs and cats. Studies have shown nose cancer is more common in larger animal breeds than in smaller ones, and it may be more common in males than females. Options exist when the disease is caught early and aggressively treated.


The condition or disease described in this medical article can affect both dogs and cats. If you would like to learn more about how this disease affects cats, please visit this page in the PetMD health library.




  • Sneezing
  • Anorexia
  • Seizures
  • Nasal discharge
  • Facial deformity
  • Pain in the nose
  • Obstructive masses in the animal's nose




A pollutant-filled environment is a known cause of nose cancer in dogs.




Veterinarians may utilize a variety of tools to detect nose cancer. A microscopic camera placed in the nose (rhinoscopy) can be used to look into the nasal cavity, although it may not be effective if blood or masses are obstructing the view. A biopsy will be done for a definitive diagnosis. A diagnosis can also be made if bacterial cultures come back positive. Material from the lymph nodes are sometimes examined to see if the disease has spread (metastasized) into other parts of the animal's body.
