The short answer
Wood dust from cutting and shaping wood is linked to cancers of the nasal cavity and sinuses. Workers who use woodworking machinery are most exposed. Exhaust ventilation and respirators can reduce exposure.
Wood dust is recognized as a carcinogen by the National Toxicology Program and IARC.
People are mainly exposed by breathing dust created when machinery cuts or shapes wood.
NCI describes strong and consistent associations with cancers of the nasal cavity and paranasal sinuses.
A carcinogen classification describes hazard — whether something can cause cancer — not your personal risk at a given exposure.

The whole article, with every detail and caution.
The simple version
Fine wood dust created when machinery cuts or shapes wood can be breathed in and is deposited in the nose, throat, and other airways. It is linked to cancers of the nasal cavity and paranasal sinuses. Woodworkers face the most exposure.
What wood dust is
Wood dust is made of tiny particles released during woodworking.
How people are exposed
Exposure mostly comes from work with wood. NCI notes that sander operators, press operators, and lathe operators in woodworking industries have especially high exposure.
The cancer connection
NCI describes strong and consistent associations between wood dust exposure and cancers of the paranasal sinuses and nasal cavity.
NCI says wood dust is recognized as a carcinogen by both the National Toxicology Program and the International Agency for Research on Cancer (IARC).
Hazard is not the same as risk
A carcinogen listing is about hazard. It means wood dust can cause cancer under some conditions. It does not measure your own risk. Risk depends on how much dust you breathe, for how long, and on other factors. Two things in the same group can carry very different real-world risks.
How to lower your exposure
- Employers can install exhaust ventilation at the points where dust is made.
- Workers can use respirators as temporary protection.
- Follow workplace exposure limits (NCI refers to OSHA guidelines).
Small, steady steps add up. To see where wood dust fits among other causes of cancer, read our overview of cancer prevention and what raises cancer risk.
The bottom line
Wood dust is recognized as a carcinogen. The most important thing you can do is understand where exposure comes from and take reasonable steps to reduce it.
Common questions
Does wood dust cause cancer?
NCI says wood dust is recognized as a carcinogen by the National Toxicology Program and IARC. How much any one person's risk rises depends on how much they are exposed to and for how long.
How are people exposed to wood dust?
Workers are exposed by breathing in dust when machinery cuts or shapes wood. Dust is deposited in the nose, throat, and other airways.
Which cancers are linked to wood dust?
NCI describes strong and consistent associations with cancers of the paranasal sinuses and nasal cavity.
How can I reduce my exposure to wood dust?
NCI says employers can use engineering controls such as exhaust ventilation at the dust source, and workers can use respirators as temporary protection. Ask your employer about workplace exposure limits.
Does a carcinogen label mean I will get cancer?
No. A classification is about hazard — whether wood dust can cause cancer under some conditions — not a prediction that any one exposed person will develop cancer. Your actual risk depends on the amount and length of exposure and other factors.

Review details and limits
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes, and this is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and then compared with the sources listed on it, looking for statements those sources do not back up. That check is not a sentence-by-sentence record and can miss errors. It is not a medical review, and it does not confirm the page is complete or right for your situation.
General education — varies by person. Answers genuinely differ between people. This page explains what commonly varies and points you to your care team for your situation.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
