It's actually not that black and white. Wood dust is linked to a statistically significant increase in the occurrence of a very rare nasal cancer. But the thing is, in woodworkers and in the general population alike, it's still a very rare cancer. You're orders of magnitude more likely to die of other cancers, whether you work with wood or not. This should be way, way down your list of risks.

There is a simpler reason to avoid wood dust: it causes allergies, asthma, and other non-cancer respiratory issues in a fair number of people.
