10ĭo we know that lung cancer is related to air pollution? Numerous epidemiological studies have shown that people living in highly polluted areas are more likely to die of lung cancer than those who live in less polluted areas. Mouse tumor formation was prevented by treatment with anti-IL1B therapy, suggesting a causal link. In mice, inhalation of PM2.5 induces an inflammatory axis driven by IL1B, which is associated with the development of lung cancer. A recent study found a significant association between PM2.5 levels and the incidence of lung cancer for 32,957 EGFR-driven lung cancer cases. In addition to causing local inflammation and oxidative stress, these particles penetrate deep into the lung’s terminal bronchioles, and from there translocate into the circulation, causing systemic inflammation. These particles have been categorized as group 1 carcinogens by the International Agency for Research on Cancer (IARC). Particulate matter (PM2.5) with diameters of less than 2.5 microns (or about 1/30th the width of a human hair) generated by fossil fuel combustion is of particular concern. In addition to greenhouse gasses, fossil fuels also emit particulate matter when burnt. In the United States, polluted areas encompass both urban and rural locales (Cohen, 2017 #61).
7 The Global Burden of Disease 2017 Risk Study calls it out as the second most common cause of lung cancer, after smoking. Ambient air pollution is blamed for 7 million deaths worldwide, one in five deaths globally. What does air pollution have to do with climate change? The burning of fossil fuels (coal, oil, and gas) is primarily responsible for air pollution, which both worsens climate change, and is worsened by climate change.Įnvironmental scientists have established that air pollution has devastating consequences.
As a call for individual and collective action, we also provide several specific steps for oncologists to consider adapting to mitigate the threats in front of us. The purpose of this editorial for the oncology community is to increase awareness of the imminent and future harms caused by climate change and fossil fuel emissions to our patients, our practices, our families and ourselves. Some of these societies have or are developing policy statements or white papers outlining how climate change will impact their patients and calling for action. These societies include as members premiere cancer organizations in which many of us are members and/or volunteers (ASCO, ASTRO, SGO).

Its nearly 50 professional member health organizations and 75 affiliates signed its consensus statement. The Medical Society Consortium for Climate and Health is a U.S.-based non-profit organization dedicated to educating the public and policymakers in government and industry about the harmful human effects of global climate change. More and more medical organizations and their members recognize the warming of the planet as a health issue. The estimates of its effects are contested, and there are disagreements about what to do, because there are people and industries with interest in taking no action. Universal, with no obvious single enemy.Complex, with no single cause, and no single solution.It requires sacrifices now to avoid uncertain losses far in the future. Its impacts occur gradually, and its solutions have no deadlines. Its bigger effects are on people far away. Daniel Kahneman, Nobel Laureate in Economics, explains why action on climate change has been so elusive.
