Tumors of the nose and sinuses can be benign (non-cancerous) or malignant (cancerous). These tumors can cause congestion, difficulty breathing, decreased smell and taste, bleeding, and pain. Often, tumors of the nose and sinuses will mimic a sinus infection. Unfortunately, this can lead to a delay in diagnosis. Usually, tumors in the nose and sinuses are benign, but often need to be surgically removed.

Cancers arising from inside the nose or sinuses are rare. They can be difficult to see and may require a fiberoptic camera examination. CT scans and MRI scans may also be required for complete evaluation. Malignant tumors of the nose and sinuses will often be treated with a combination of chemotherapy, radiation therapy, and surgery.
