Paranasal Sinus and Nasal Cavity Cancer

How Is Cancer of the Paranasal Sinus and Nasal Cavity Diagnosed?

A doctor will typically take your medical history and do a physical exam. The physical exam will include looking at your eyes, ears, nose, mouth, face, neck, and throat. Any details you can provide about any pain you are experiencing, such as whether it’s sharp, burning, dull, or achy, where it’s located, and when it occurs, can help with the diagnosis.

Your doctor might order an endoscopy of your sinuses. This is a procedure in which a thin tube with a tiny light and a video camera on the end is inserted into your sinuses. Looking inside your sinuses will help your doctor to pinpoint the location and size of the tumor.

Your doctor might order these tests, as well:

  • Blood tests
  • Imaging tests of your skull, such as X-rays of the sinuses
  • Imaging tests of your chest
  • Biopsy, in which a small sample of the tissue from the tumor is removed and examined in the lab for signs of cancer
