In short
The nasal cavity is the passageway just behind the nose through which air passes to the throat, while the paranasal sinuses are small hollow mucus-producing spaces around the nose. Cancer of the nasal cavity and paranasal sinuses is rare, with greater risk associated with being male and over 40 years old, smoking, having an HPV infection, or being exposed to certain workplace chemicals. There may be no symptoms at first, but doctors can diagnose the condition using imaging tests, biopsies, and lighted tube-like instruments that look inside the nose. Treatment options for this cancer include surgery, radiation, and chemotherapy.

Description
Your paranasal sinuses are small hollow spaces around the nose. They are lined with cells that make mucus, which keeps your nose from drying out. The nasal cavity is the passageway just behind your nose. Air passes through it on the way to your throat as you breathe.
Cancer of the nasal cavity and paranasal sinuses is rare. You are at greater risk if you are:
- Male and over 40 years old
- Exposed to certain workplace chemicals
- Infected with HPV
- A smoker
There may be no symptoms at first, and later symptoms can be like those of infections. Doctors diagnose nasal cancer with imaging tests, lighted tube-like instruments that look inside the nose, and biopsies. Treatment options include surgery, radiation, and chemotherapy.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.
Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.
What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.
Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
In an emergency, call 112 (or your local emergency number). Do not delay seeking medical help because of something you read here.
