Symptoms of Nasal Adenocarcinoma in Dogs

Source: PetWave, Updated on July 16, 2015
Nasal Adenocarcinoma

Effects of Nose Cancer

The symptoms of canine adenocarcinoma will vary depending upon which glandular tissue is affected, the severity and extent of infiltration and metastasis and the dog’s overall systemic health - especially the functional strength of its immune system. Nasal adenocarcinoma tends to show a fairly consistent constellation of clinical signs.

Symptoms of Nasal Adenocarcinoma

Nasal adenocarcinoma usually involves the slow, progressive, local invasion of the lining of the nasal cavities by neoplastic glandular cells. Typically, one nasal cavity is affected first, and then the other becomes involved. Symptoms may include:

  • Nasal discharge – unilateral and/or bilateral (coming from only one or from both nostrils); +/- mucus and/or pus (mucopurulent nasal discharge); +/- fresh blood (hemorrhagic nasal discharge); +/- thin, watery (serous) nasal discharge
  • Nose bleeds (epistaxis) – intermittent and progressive; unilateral and/or bilateral (coming from one or both nostrils)
  • Excessive tearing (abnormal overflow of tears; epiphora)
  • Malpositioned eyes (abnormal protrusion or bulging of the eyes; exopthalmos)
  • Sneezing and/or reverse sneezing
  • Bad breath (halitosis)
  • Lack of appetite (inappetance; anorexia)
  • Seizures (with metastasis to brain tissue)
  • Facial deformities (space-occupying masses; bony changes)
  • Deformation of the hard palate
  • Deformation of the upper jaw (maxilla)
  • Pain (especially on nasal sinus examination or when the mouth is opened)
  • Blocked nasal passages (obstructed nostrils/nares)
  • Difficulty breathing (dyspnea) through one or both nostrils (physical airflow obstruction)
  • Enlarged lymph nodes (especially mandibular lymph nodes)

Dogs at Increased Risk

Mid-sized to large breed dogs appear to have an increased risk of developing nasal adenocarcinoma, and there also may be a slightly increased risk in males, although the reasons for these reported predispositions are not well-understood. As with many types of cancer, older animals are more commonly affected.

Lead Poisoning

Dogs can be poisoned when they ingest lead – especially if they have repeated exposure to the substance. Lead is found in a number of places and in a number of different things
