Connecting the Dots: The Role of Pollution in Lung Cancer Onset

A disproportionately large number of cancer-related deaths are caused by lung cancer, making it a worldwide public health concern. Lung cancer has a complex etiology, although carcinogenic chemicals are key contributors. In this chapter, we delve into the complex web of connections between carcinogenic pollution and the development of lung cancer. An overview of lung cancer, its prevalence, causative factors, and its various subtypes is covered to begin with. A focused discussion of carcinogenic pollutants, their diverse sources encompassing air pollutants, industrial emissions, indoor contaminants, lifestyle-related exposures, and mechanisms of action is also covered. The article delves into factors that have been proven to increase the risk of lung cancer, such as cigarette smoking, air pollutants, occupational risks, and interior pollutants. The chapter delves further into the topic, explaining how environmental influences and genetic predisposition interact in intricate ways. There is extensive citation and reporting of epidemiological, case-control, and cohort research that have confirmed the link between exposure to carcinogenic pollutants and the occurrence of lung cancer. As the chapter progresses, it also explores preventive measures and interventions, including environmental regulations, public health policies, and lifestyle modifications, aimed at reducing pollutant exposure and mitigating lung cancer risk. It provides valuable insights for clinicians, researchers, policymakers, and the general public, facilitating a collective effort to prevent or combat this formidable disease.
