Signs and Symptoms

The symptoms can vary depending on which sinuses are affected.
The most common symptoms include:
* blocked sinuses which do not clear
* pain behind the nose or in the upper teeth
* swelling around the eyes.
Other symptoms may include:
* numbness of the cheek, upper lip, upper teeth or side of the nose
* persistent nosebleeds* headaches
* speech changes
* double vision.
These symptoms may occur due to conditions other than cancer, and most people with these symptoms will not have paranasal sinus cancer. However, like most cancers, paranasal sinus cancer is most likely to be cured when diagnosed at an early stage.Therefore, any of the above symptoms should be reported to your GP if they do not improve over a few days.
