A recent scientific study revealed a possible association between air pollution and the development of lung cancer, even among people who have never smoked, which re -asks questions about the profound impact of environmental factors on human health.
The study, whose results were conveyed “Sky News Arabia”, was based on regional data on air pollution, and focused on the micro -molecules known as the PM2.5, which penetrate into the lungs when inhaled, and may reach the bloodstream, updating changes in cells that may be related to the emergence of cancer.

The researchers based on the study explained that relying on air pollution data at the level of regions, not at the level of individuals, raises scientific challenges when explaining the results, as it is difficult to determine the extent of each individual exposure to these fine molecules, which opens the way for the possibilities of other factors in the interpretation of the relationship between exposure to pollution and lung cancer.
They also pointed out that the accuracy of the participants’ statements about their personal history with smoking may affect the credibility of the results, especially since smoking is still one of the most prominent factors known to develop this type of cancer.
Despite these methodological restrictions, scientists believe that what has been reached is additional support for the hypothesis that air pollution can play a role in the development of lung cancer, through genetic mechanisms similar to those caused by smoking.
The research team has indicated that the micro -molecules resulting from vehicle exhaust, industrial emissions and forest fires may cause chronic mutations or infections that over time lead to cellular cells that cause cancer.
In this context, the epidemic, Dr. Maria Theresa Landy of the National Cancer Institute, confirmed that the results put the international community in front of a major health challenge that requires an urgent scientific and preventive move, and said: “We have to better understand the relationship between air pollution and lung cancer injuries in non -smokers, because we are facing a growing, growing, unable to be ignored.”
She pointed out that future research should focus on assessing individual exposure more accurately, in addition to studying genetic and environmental reactions, to determine the mechanisms that link pollution and injury.
In recent years, voices demanding tightening air quality standards globally, especially in major cities that suffer from high levels of pollution, and the World Health Organization reports indicate that millions of people around the world are exposed daily to harmful concentrations of fine molecules, which are one of the factors that cause chronic pathogens, including cancer, heart and lung diseases.
In light of these data, the specialists believe that the results of the recent study constitutes an invitation to enhance cooperation between researchers and health and environmental policies, in order to protect the population, especially the most vulnerable groups, such as children and the elderly, and the population of crowded urban areas, the deep understanding of the relationship between pollution and lung cancer may pave the way for effective preventive measures, and contributes to reducing the burden of this disease on public health.
