Your nose widens from a narrow tube in the nostrils to a wide nasal cavity which sits in the space between the nostrils and above the roof of the mouth, from where it curves down to the back of the throat.
Paranasal is the medical term for the area around the nose. This area contains spaces of air called sinuses aournd the nose and behind the cheekbones.
The links on this page will help you to find out more about cancers of the nose and sinuses.

If you have been affected by cancer in some way and would like to talk to someone about what you have read or need help finding information - you are welcome to drop into any Maggie’s Centre or to visit Maggie’s Online Centre and talk with a cancer support specialist.
