What causes sinus or nasal cancer?
While doctors know that certain risk factors may make a person more likely to develop sinonasal cancer, the exact cause of most cancers is unknown. Cancers develop when genes that control cell growth and division become defective. Some people may have inherit certain gene defects or mutations from their parents, however, most mutations probably occur during a patient’s lifetime, rather than being present from birth. These mutations probably occur after exposure to certain risk factors described above, or they may occur for no apparent reason.
