Yes, cancer can develop inside your nose. It’s uncommon, but tumors do form in the nasal cavity and the air-filled spaces behind it called the paranasal sinuses. These cancers account for a small fraction of all head and neck cancers, and because early symptoms often mimic a stubborn sinus infection, they’re frequently caught late. Here’s what you should know.
Types of Nasal Cancer
The most common form is squamous cell carcinoma, which grows from the thin, flat cells lining the inside of the nasal passages and sinuses. But several other types can appear in this area. Melanoma, the same cancer typically associated with sun-exposed skin, can start in pigment-producing cells inside the nose. Sarcomas grow from muscle or connective tissue. And a type of benign growth called an inverting papilloma can, in a small number of cases, turn cancerous over time.
Mucosal melanoma of the nose is particularly aggressive. Most people with this subtype show up with one-sided nasal blockage, nosebleeds, or both. Three-year overall survival for sinonasal mucosal melanoma treated with curative intent is around 40%, making early detection critical.
Symptoms That Look Like a Sinus Problem
The tricky part of nasal cancer is that it starts with symptoms nearly everyone has experienced: a stuffy nose, pressure in the face, occasional nosebleeds. That overlap with common sinus infections is one reason these cancers are often diagnosed at a later stage. A few patterns, though, are worth paying attention to.
Congestion or blockage that affects only one side of the nose, nosebleeds that keep recurring without a clear cause, facial numbness, persistent pain or pressure that doesn’t improve with typical sinus treatments, and a lump or mass you can feel inside the nose or on the face are all signals that something beyond a routine infection could be going on. None of these guarantees cancer, but any symptom that lingers for weeks without explanation deserves a closer look.
What Increases the Risk
Most people who develop nasal cancer have been exposed to specific workplace hazards over many years. Wood dust is the single most important occupational risk factor, especially for a subtype called adenocarcinoma. People who work in carpentry, furniture manufacturing, or sawmills face the highest exposure. Leather dust in shoe and boot manufacturing carries a similar risk.
Dust and fumes from nickel refining (specifically nickel sulfides and oxides) and chemicals used in producing isopropyl alcohol through the strong acid process are also established risk factors. Chromium, formaldehyde, and textile dust are suspected but not yet confirmed contributors.
Beyond the workplace, about 30% of nasal and paranasal sinus cancers are linked to HPV, the human papillomavirus. Smoking also raises risk, though not as dramatically as it does for lung cancer.
How It’s Diagnosed
If your doctor suspects something unusual, the first step is typically a nasal endoscopy. A thin, flexible tube with a light and camera is inserted into the nose to get a detailed view of the nasal passages and sinuses. If anything looks suspicious, a biopsy follows. This can be done during the same endoscopy using small instruments threaded through the tube, or with a needle inserted directly into a mass.
Imaging comes next to determine how far a tumor has spread. CT scans and MRIs show the size and location of the growth and whether it has reached nearby structures like the eye socket, the roof of the mouth, or the base of the skull. A PET scan may be added to check for spread to distant areas of the body.
Staging and What It Means for Outlook
Nasal cancers are staged based on how far the tumor has extended into surrounding structures. A stage 1 tumor is confined to a single area within the nasal cavity or sinuses. Stage 2 means the tumor has grown into a neighboring section of the nasal complex. By stage 3, it has reached the eye socket floor, the roof of the mouth, or the maxillary sinus. Stage 4 involves invasion into deeper structures like the skin of the cheek, the front of the eye socket, or the base of the skull.
Survival rates reflect this progression clearly. For cancers caught at stage 1 or 2, about 80% of people survive five years or more. At stages 3 and 4, that drops to just over 35%. Across all stages combined, the five-year survival rate sits around 50%, according to data from Cancer Research UK covering patients diagnosed between 2014 and 2016. The gap between early and late detection is one of the starkest in cancer medicine, which is why persistent one-sided nasal symptoms shouldn’t be brushed off.
Treatment
For the earliest tumors, surgery or radiation alone can be enough. But for most nasal cancers, treatment involves both. The typical sequence is surgery first to remove as much of the tumor as possible, followed by radiation to target any remaining cancer cells.
Surgery ranges from relatively limited procedures to extensive operations depending on how far the cancer has spread. Some tumors can be removed through the nose. Others require approaches that access the sinuses through the face or, in advanced cases, through the base of the skull. If cancer has spread to lymph nodes in the neck, those may need to be removed as well.
Chemotherapy plays a supporting role. It’s sometimes used before surgery to shrink a tumor and make it easier to remove, or alongside radiation for cancers that can’t be fully operated on. For recurrent squamous cell cancers, chemotherapy can help control the disease and manage symptoms even when a cure isn’t possible.
Reducing Your Risk at Work
Because the strongest risk factors are occupational, prevention centers on workplace safety. If you work around wood dust, leather dust, or nickel compounds, proper ventilation systems with dust collectors at the source of exposure are the most effective protection. Respirators offer a shorter-term solution when engineering controls aren’t fully in place. U.S. workplace safety regulations set specific exposure limits for wood dust, and employers in high-risk industries are required to meet them. If you’ve spent years in one of these environments, mentioning it to your doctor gives them a reason to take persistent nasal symptoms more seriously.
