Throat Cancer

Cancer can also affect the throat (the pharynx). The pharynx is a hollow tube about 5 inches long that starts behind the nose and goes down to the neck to become part of the oesophagus, the tube that goes to the stomach. Air and food pass through the pharynx on the way to the windpipe (trachea) or the oesophagus.

Cancer of the Paranasal Sinus and Nasal Cavity

The paranasal sinuses are small hollow spaces around the nose. The sinuses are also a space through which the voice can echo to make sounds when a person talks or sings. The nasal cavity is the air passageway through which air passes to the throat during breathing.
