What is sinus cancer?

Sinus cancer is cancer that grows in your sinuses. It usually happens in the sinuses right beside your nose or behind the bridge of your nose (the maxillary and ethmoid sinuses).

  • Sinus cancer happens most often in people from Japan and South Africa—it’s rare in other groups

  • Doctors don’t know what causes sinus cancer but think it may be related to breathing in certain types of wood and metal dust—it isn’t caused by sinus infections

  • You may not have symptoms until the cancer has grown and pushes on other structures

  • To treat sinus cancer, doctors do surgery and radiation therapy

What are the symptoms of sinus cancer?

The sinuses have empty space in which cancer can grow without pressing on anything. For this reason, you may not have any symptoms at first.

Once the cancer has grown larger, you may have symptoms such as:

  • Pain or numbness and tingling in your face

  • Feeling like your nose is blocked

  • Having a runny nose

  • Headache

  • Double vision (when you see two of the same object)

  • Nosebleeds

  • Loose upper teeth

How can doctors tell if I have sinus cancer?

How do doctors treat sinus cancer?

Sometimes surgery changes the shape or look of your face. Doctors will use the latest methods to keep the way you look as unchanged as possible.

  • Loss of taste

  • Dry mouth

  • Trouble swallowing and speaking

  • Dental problems, if your teeth were exposed to radiation
