Causes of Paranasal Sinus Tumors
A paranasal sinus tumor is a cancer that has grown inside your sinuses, the open spaces behind your nose. This tumor can begin in the cells of the membranes, bones, or nerves that line the area. You might not know or even suspect that a tumor is growing until it spreads. The sooner you get a diagnosis and start treatment, the better your chances of beating the cancer are likely to be.
