Nasal and sinus cancer

Also called Sinonasal cancer

Nasal and sinus cancer is a rare cancer that affects the space behind the nose (nasal cavity) and the air-filled spaces around it (sinuses). Early symptoms are similar to common conditions such as a cold or sinusitis, but usually affect only one side and do not go away. Exposure to some wood, leather and industrial dusts, and smoking, increase the risk.

What it is

Treatment depends on the size and position and may include surgery, radiotherapy and chemotherapy.

A blocked nose on one side that lasts more than 3 weeks should be checked.

Common signs

  • A blocked nose on one side that does not go away
  • Nosebleeds
  • Mucus running from the nose or down the throat
  • Loss of smell
  • Pain or numbness in the face
  • Swelling or watering of one eye

How it is usually diagnosed

  • Examination of the nose with a camera (nasendoscopy)
  • CT or MRI scan
  • Biopsy

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Endoscopy and biopsy reports
  • Scan reports
  • ENT and oncology letters
  • Work history and dust exposure details

Questions to ask your doctor

  • What stage is the cancer?
  • How will treatment affect my face and senses?
  • Was my work a factor?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Sudden changes in vision, a nosebleed that will not stop, or severe swelling of the face: get urgent medical help
