World Lung Day provides an opportunity for the respiratory community to reflect on the devastating impact of chronic respiratory diseases (CRDs) such as asthma, tuberculosis, and lung cancer. These diseases continue to be the leading causes of disability and death worldwide. As a cancer pulmonologist, Rivera has witnessed the devastating consequences of lung cancer on patients and their families. It is the second most common and deadliest cancer in the US. Each year, lung cancer claims more lives than colon, breast, and prostate cancers combined. On this day, as a global respiratory community, they must take action to promote lung health as a fundamental human right. The American Thoracic Society (ATS), as a founding member of the Forum of International Respiratory Societies, is raising awareness and addressing the disproportionate burden of lung disease on low- and middle-income countries. Through advocacy, collaboration, and education, they strive to improve global health outcomes and address the social and environmental determinants of health, including tobacco use and climate change.
