Most Lung Cancers are only diagnosed when it's already too late. Wood burning produces carcinogenic PM2.5s - tiny nano-particles that penetrate deep into the lungs where they can cause cancer. If you've had even a minor cough for a few weeks get it checked. Early detection could save your life. Children are at higher risk than adults as they breathe faster (inhaling even more particles) and their immune systems are not fully developed. Every year 35 000 people die of Lung Cancer. 38.7% have never smoked cigarettes - they get it from air pollution like this: Wood smoke from a domestic wood boiler.
