A staggering 99% of the population is breathing air that exceeds safe quality limits set by the World Health Organization (WHO). This polluted air, filled with fine particulate matter from various sources like fossil fuel combustion, wildfires, and construction sites, poses significant health risks – notably, an increased risk of cancer. This episode of "Let's talk cancer" delves into this public health crisis with Dr Maria Neira, Director of Public Health, Environmental and Social Determinants of Health at WHO.
