Does anyone think being exposed to smoke from doing a wood burning stove could cause irritation in cells similar to cigarette smoking. My husband has fired a wood burning stove for over 30 years 2-3 times a day throughout our cold winters in MN. It not only heats our house but also a huge building next store so there is a lot of wood thrown in. (I know from times I have tried to help out but usually end up burning the ends of my hair.) If there is any chance it could of caused his rare cancer since he has never smoked or drank? I sure would hate to keep exposing him to an irritate.
