The World Health Organization has identified air pollution as a human carcinogen, prompting many countries to implement monitoring systems for ambient particulate matter (PM). PM consists of a complex mix of organic and inorganic particles, both solid and liquid, present in the air. Given the carcinogenic properties of PM and the prevalence of lung cancer in exposed populations, it is crucial to explore their connection and clinical implications to effectively prevent lung cancer in this group. This review examines the link between ambient PM and lung cancer. Epidemiological studies have shown a dose-response relationship between PM exposure and lung cancer risk. PM exposure leads to oxidative stress, disrupting the body's redox balance and causing DNA damage, a key factor in cancer development. Recent findings on the strong correlation between ambient PM and adenocarcinoma suggest that understanding the specific molecular and pathological background of pollution-related lung cancer is important.
