Living with Extranodal nasal NK/T cell lymphoma

A rare cancer that usually starts in the nose, sinuses, or upper airway, mostly in men in their 50s.

Understanding Extranodal nasal NK/T cell lymphoma

Extranodal nasal NK/T cell lymphoma (NKTCL) is a rare type of cancer that usually starts in the nose, sinuses, eyes, or upper airway.

It mostly affects men in their 50s. It can cause a hole in the roof of the mouth and sores that damage the face or upper airway. In advanced stages it can spread to other parts of the body, which makes it harder to treat. Some cases start in the lymph nodes.

Signs & symptoms

GARD describes these symptoms in its summary:

  • A mass in the nose
  • Nasal bleeding
  • Trouble breathing through the nose
  • A hole in the roof of the mouth
  • Sores that damage the face or upper airway

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
