Air pollution could trigger lung cancer.
Air Pollution is increasing day by day we all know due to the Vehicle emissions, fuel oils and natural gas to heat homes, by-products of manufacturing and power generation, particularly coal-fueled power plants, and fumes from chemical production are the primary sources of human-made air pollution.Vehicle emissions, fuel oils and natural gas to heat homes, by-products of manufacturing and power generation, particularly coal-fueled power plants, and fumes from chemical production are the primary sources of human-made air pollution.Air pollution refers to the release of pollutants into the air—pollutants which are detrimental to human health and the planet as a whole. According to the World Health Organization (WHO), each year air pollution is responsible for nearly 7 million deaths around the globe.
Scientists have discovered a new mechanism through which very small pollutant particles in the air may trigger lung cancer, even for those who have never smoked before.This identification could now be used to develop new prevention measures or even therapies for lung cancer. The particles, which are typically located in the exhausts of vehicles and fossil fuel smoke, are associated with non-small cell lung cancer risk. This is the most common form of lung cancer, accounting for over 250,000 lung cancer deaths globally each year.Research is ongoing, but according to 2014 study Source suggests that long-term exposure to air pollution can cause damage to DNA, mutations, and altered gene expression. These changes may cause the cells of the lungs to grow uncontrollably.
To reduce outdoor air pollution, industries will need to invest in clean technologies to reduce smokestack emissions and improve waste management. Cities will need to invest in rapid urban transit, and walking and cycling networks that help reduce the number of cars on the road, among other measures.
