Nasal Adenocarcinoma

Definition of Nasal Adenocarcinoma

Nasal adenocarcinoma is a slow, progressive, local infiltration by cancer cells of tissues lining the inside of the nose. Most nasal adenocarcinomas in dogs start on one side of the nasal sinuses but ultimately spread to both sides. Adenocarcinoma is the most common cause of nasal cancer in dogs. The cause of nasal adenocarcinoma is not known. Chronic exposure to environmental pollutants has been suggested as a possible contributing factor in dogs that spend a lot of time in urban settings. Exposure to secondhand smoke, wood dust and/or toxins from industrial factories have been weakly linked to nasal tumors. Genetics almost certainly play a role. Dogs with nasal adenocarcinoma usually have a discharge coming from their nose, which may contain mucus, pus and/or blood. They often develop lumps on their face, protrusion of one or both eyes, excessive tearing, sneezing, bad breath and spontaneous nosebleeds.
