Ask an oncologist or an occupational-health specialist what causes cancer of the nose and sinuses, and the first answers will be about a workbench, not an ashtray: sawdust in a cabinet shop, nickel and chromium in a plating plant, leather dust in a tannery, the formaldehyde fumes of an embalming room. Nasal and paranasal sinus cancer is the textbook occupational cancer, and that reputation is earned. But it has quietly buried a second cause that carries at least as much weight in the ordinary case. The International Agency for Research on Cancer — the cancer arm of the World Health Organization — concluded that there is sufficient evidence in humans that tobacco smoking causes cancer of the nasal cavity and paranasal sinuses, first in its 2002 review of tobacco and again when it reaffirmed the finding in 2012. For a longtime smoker who develops one of these cancers, “it must have been the job” is not the end of the story. It is often the tobacco defendant's favorite argument.
This piece continues the firm's series on the cancers cigarettes cause, and it completes the map of the head-and-neck “corridor” the smoke passes through. It sits beside our guides to oral and throat cancer and laryngeal (voice box) cancer, and it begins where the airway begins, above the mouth, at the tissues nearest the point of entry — the far end of the same passage that ends in the lungs. Below: what these cancers are and why the anatomy is unusual, why they sit on the list of cancers smoking causes, how large the smoking risk is, the distinctive occupational overlap that makes these cases different, the “it was your job, not our cigarettes” defense, and how a smoking-related nasal or sinus cancer claim fits the same liability framework the firm uses in its lung cancer, COPD, and other smoking-disease matters.
What Nasal and Paranasal Sinus Cancer Are
These are cancers of the space behind the nose and the air-filled cavities around it. The nasal cavity is the hollow passage just behind the nose through which air first travels on its way in. The paranasal sinuses are the connected air pockets in the bones of the face and skull — the maxillary sinuses in the cheeks, the ethmoid sinuses between the eyes, the frontal sinuses in the forehead, and the sphenoid sinuses deeper behind them. Cancer can arise from the lining of any of these spaces, and the maxillary sinus and the nasal cavity are the most common sites.
Several cell types occur here, but the most common in the nasal cavity is squamous cell carcinoma, arising from the flat cells that line the surface — and, as with the mouth, throat, and voice box, it is the squamous cell type that the American Cancer Society specifically ties to smoking. These are uncommon cancers, and their early symptoms are easy to dismiss as a lingering cold or a sinus problem: nasal blockage or congestion on one side that will not clear, nosebleeds, a reduced sense of smell, facial pain or numbness, a lump on the face or in the neck, or changes in vision as a tumor presses toward the eye. Because they are rare and their warning signs are so ordinary, they are frequently found late — and in a person with a long smoking history, every factor that contributed deserves a careful look.
Why Nasal and Sinus Cancer Are on the List of Cancers Smoking Causes
The causal link here does not rest on the U.S. Surgeon General's earliest reports the way lung and oral cancer do — it rests on a later and equally authoritative source. The International Agency for Research on Cancer evaluated the world's epidemiological evidence and concluded that tobacco smoking causes cancer of the nasal cavity and paranasal sinuses. This was not on IARC's list in its 1986 review, which named lung, oral cavity, pharynx, larynx, esophagus, pancreas, bladder, and renal pelvis; nasal and sinus cancer was added in 2002 once the accumulated evidence was strong enough, and the conclusion was reaffirmed in the agency's 2012 monograph. The American Cancer Society, in turn, tells the public plainly that smoking increases the risk of nasal cavity cancer, specifically the squamous cell type.
The biology fits the anatomy. Inhaled tobacco smoke does not confine itself to the mouth and throat on its way to the lungs; it passes through and around the nasal cavity, and its carcinogens — including tobacco-specific nitrosamines and formaldehyde, the latter also a recognized cause of nasal cancer on its own — settle on and are absorbed by the lining of these spaces. Over years of exposure, that repeated chemical assault damages the DNA of the squamous cells the same way it does in the neighboring tissues of the mouth and throat and larynx. It is the same carcinogen chemistry the firm describes throughout this series — here, applied to the tissues nearest the very start of the airway.
How Big Is the Smoking Risk?
Meaningful, dose-dependent, and reversible over time with cessation. The epidemiological studies IARC reviewed found roughly a doubling of the risk of nasal cancer among heavy or long-term smokers compared with people who never smoked, with the excess risk falling among those who quit long ago. The following points come from the IARC evaluations and the American Cancer Society:
- About double the risk of nasal cavity and paranasal sinus cancer among heavy or long-term smokers compared with never-smokers, per the epidemiology IARC reviewed — with the risk rising with the amount smoked and the years of smoking.
- The excess risk declines among long-term quitters, the mirror image of the dose-response gradient — a pattern epidemiologists treat as a signature of genuine causation rather than coincidence.
- Smoking is most clearly tied to the squamous cell type of nasal cavity cancer, per the American Cancer Society, rather than to every histology equally.
- These cancers are rare, and the American Cancer Society notes that many patients have no identified risk factor at all — which is precisely why a documented, substantial smoking history carries weight when it is present.
A roughly twofold increase in a cancer this uncommon is not a rounding error. Where a heavy, long-term smoker develops a squamous cell cancer of the nasal cavity, tobacco belongs on the short list of causes that actually explain the disease — a conclusion an authority as cautious as IARC reached only after the evidence demanded it.
A Distinctive Fact: The Occupational Overlap
Every cancer in this series carries some competing explanation the tobacco industry can point to — alcohol for the mouth, HPV for the throat, hepatitis for the liver. Nasal and sinus cancer carries the strongest competing story of all, and it is legitimate: this is the classic occupational cancer. The American Cancer Society links it to a long list of workplace exposures, including wood dust from carpentry, dust from textiles, leather dust, flour, nickel and chromium dust, formaldehyde, mustard gas, and radium. A cabinetmaker, a shoemaker, a metal-plater, a baker, or an embalmer who develops this cancer may well have a job-related exposure in the picture.
That overlap is exactly what makes these cases turn on a careful reading of the whole record rather than a single fact. A smoking history and an occupational history are not rivals for a single “the” cause; both can be real, and both can contribute to the same tumor. Sorting out which exposures a particular patient actually had, over how many years, and how they line up with the tumor's site and cell type is the kind of work that decides how — and whether — a claim is built.
This is where the firm's Medical-Legal Expert earns his place. Herb Borroto, M.D., J.D., who holds both a medical degree and a law degree, reads the pathology and histology reports, the tumor's site within the nasal cavity or a specific sinus, the cell type, and the smoking and occupational history together — recognizing when a squamous cell tumor in a longtime smoker points to tobacco as a substantial contributing cause, in a way a purely legal review has no reason to look for and a purely clinical review has no reason to connect to liability.
The Defense: “It Was Your Job, Not Our Cigarettes”
Because nasal and sinus cancer has a genuine occupational profile, expect the tobacco defendants to lean on it hard: he was a carpenter for thirty years — the wood dust did this, not our product. The argument trades on a real association. It still falls short of ending a case.
Smoking is an independent, IARC-recognized cause of these cancers; it does not stop being a cause because another recognized carcinogen was also present. In product-liability law, a manufacturer whose product was a substantial contributing factor to an injury does not escape responsibility by naming another factor that also contributed. Where the workplace exposure and the cigarettes both acted on the same tissue over the same decades, the sound question is not which one caused the cancer but whether the cigarettes were a substantial factor in causing it — and IARC's causal conclusion is the starting point for showing they were. This mirrors the “it was the drinking” and “it was the HPV” deflections the firm answers in its oral and throat cancer guide: a second cause is a fact to be accounted for, not a defense that clears the product.
The Legal Framework
Smoking-related nasal and paranasal sinus cancer cases proceed on the same liability theories as other smoking-disease cases against the tobacco industry:
- Negligent design, manufacture, and marketing of cigarettes.
- Strict product liability for an unreasonably dangerous product.
- Failure to warn about the full range of cancers smoking causes — including cancers, like those of the nose and sinuses, that appear on no cigarette warning label and in almost no public-health campaign.
- Fraud and misrepresentation about the safety and addictiveness of the products.
- Civil conspiracy among manufacturers to suppress and distort health research.
The internal industry records unearthed in prior tobacco litigation — the documents showing what the companies knew about the harms of their product and when — remain central evidence. Our companion piece on how tobacco companies hid the truth walks through that record. Alex Alvarez, the firm's Managing Partner and a Board Certified Civil Trial Lawyer, brings that documentary history together with each client's own smoking, occupational, and medical records to build the causation case a nasal or sinus cancer claim requires, and to answer the “it was your job” defense described above.
What a Nasal or Sinus Cancer Case Needs
- Documentation of the diagnosis — the biopsy or surgical pathology confirming the cancer, the exact site (nasal cavity or which paranasal sinus), the cell type (squamous cell versus another histology), and the staging.
- A substantial smoking history, measured in pack-years, spanning the years the science associates with the disease.
- A careful occupational history — the jobs held, the materials worked with, and for how long — so any workplace exposure can be shown alongside the smoking contribution rather than used to erase it.
- Brand identification — which cigarettes or tobacco products were used, and for how long.
- Causation testimony from an appropriate expert familiar with the smoking–sinonasal cancer literature.
- Documentation of the disease's impact — the surgery (which in this region can affect the face, sinuses, and eye), chemotherapy or radiation, any recurrence, and, in cases brought after a death, the cause-of-death records.
The unglamorous paperwork behind these elements is what carries a case. Our guide to smoking history documentation covers the records that build or break a tobacco claim, and our wrongful death family guide walks through what a family should know when nasal or sinus cancer has taken a loved one.
The Jurisdictions We Serve
The Alvarez Law Firm represents smokers and families in Hawaii, Illinois, Nevada, Oregon, Pennsylvania, and the U.S. Virgin Islands. Each of those jurisdictions has its own filing deadlines, its own substantive law on tobacco product liability, and its own version of the discovery rule — how long after a diagnosis, or a death, a claim must be filed. Because those deadlines are unforgiving and easy to overlook while a family is absorbed in treatment, talk to counsel licensed in the relevant state about how they apply to your situation. Waiting can foreclose options that were available earlier.
Frequently Asked Questions
Does smoking cause nasal cavity and paranasal sinus cancer?
Yes. The International Agency for Research on Cancer (IARC), the cancer agency of the World Health Organization, concluded that there is sufficient evidence in humans that tobacco smoking causes cancer of the nasal cavity and paranasal sinuses, first in its 2002 monograph and again when it reaffirmed the finding in 2012. The American Cancer Society states that smoking increases the risk of nasal cavity cancer, specifically the squamous cell type. These are rare cancers, and many patients have no identified cause, so a longtime smoker who develops one should have the record reviewed by counsel.
How much does smoking raise the risk of nasal and sinus cancer?
Epidemiological studies reviewed by IARC found roughly a doubling of the risk of nasal cancer among heavy or long-term smokers compared with never-smokers, with the excess risk falling among people who quit long ago. The risk is dose-related, rising with the number of cigarettes smoked and the number of years of smoking. Because these cancers are uncommon and often involve workplace exposures as well, the tumor's cell type, the smoking history measured in pack-years, and any occupational exposure history all matter to how a case is evaluated.
Can you file a lawsuit if a job exposure may also have contributed to the sinus cancer?
Potentially. Nasal and sinus cancer is strongly associated with workplace dusts and chemicals such as wood dust, leather and textile dust, nickel and chromium, and formaldehyde, so tobacco defendants often argue it was the job, not the cigarettes. But smoking is an independent, IARC-recognized cause, and product-liability law does not excuse a manufacturer whose product was a substantial contributing factor merely because another exposure also contributed. A longtime smoker diagnosed with nasal or sinus cancer, or a family that lost someone to it, should speak with counsel licensed in the relevant state, because every jurisdiction has its own filing deadline.
