A study reports an increased risk of developing some form of lung cancer as air pollution increases

پژوهشی از افزایش خطر ابتلا به نوعی از سرطان ریه با بیشتر شدن آلودگی هوا خبر می‌دهد

An international team of researchers has found a link between increased air pollution and an increased incidence of lung adenocarcinoma (a type of lung cancer). In the same study, the team concluded that with reduced tobacco use worldwide, fewer people developed squamous cell carcinoma of the lung.

Lung adenocarcinoma is a common type of lung cancer in which genetic, environmental and lifestyle factors play an important role. Pulmonary squamous cell carcinoma, on the other hand, depends more on a person’s smoking background.

this study Showed that an increase of 0.1 micrograms per cubic meter of soot in the Earth’s atmosphere has increased the incidence of lung adenocarcinoma to 12% worldwide. Carbon soot is a pollutant that is classified as PM2.5 and increased by about 3.6 micrograms per cubic meter worldwide between 1990 and 2012.

In the same years, a 0.26 percent reduction in world tobacco use led to a 6 percent reduction in lung squamous cell carcinoma. Lung cancer killed 1.8 million people worldwide by 2020 and has long been the leading cause of cancer worldwide.

The relationship between lung cancer and carbon dioxide also changes with the gender of the people and the continent in which they live. Overall, an increase of 0.1 micrograms per cubic meter of carbon per year resulted in a 14 percent increase in adenocarcinoma in women and a 9 percent increase in men. The same amount of soot increase per year led to a 14 percent increase in the incidence of squamous cell carcinoma in women, leading to an 8 percent increase in the incidence in men.

In addition, the same amount of annual soot increase in North America increased adenocarcinoma incidence by 10 percent, while in Europe it increased it by up to seven percent. These data generally show that men have a greater reduction in the incidence of squamous cell carcinoma, and this has coincided with a reduction in smoking worldwide.

Despite declining global tobacco use, the number of women in North America, Asia-Pacific who smoke or smoke has risen by as much as 1 percent, leading to a 12 percent increase in their lung stones.


However, despite the fact that the percentage of smokers in the world has decreased, between 1980 and 2012, the world’s population has increased significantly, and this has led to an increase in the number of smokers. In this regard, the number of women who smoke has increased by seven percent.

With the rise of pollutants such as soot and sulfate in Asia, the incidence of lung adenocarcinoma here is much higher than on other continents, at 24 percent annually. Japan tops the deadly table with an annual increase of 38% and South Korea with 37% annually.

The researchers calculated the amount of pollutants on the continent and found that carbon dioxide increased by 11.9 micrograms per cubic meter per year and sulfate by 35.4 micrograms per cubic meter per year, with South Korea having the highest increase among Asian countries. .

The use of fossil fuels for energy production or transportation has long been known as a source of pollutants in cities, and even exacerbates the effects of climate change by producing carbon dioxide. The results of this study gave us the necessary warnings and now we must move to better control this pollution.

Air pollution and climate change are two major environmental hazards to human health. The results of this research can help policies to control air pollution on all continents so that we can get rid of this situation as soon as possible.
