CANCER-CAUSING AIR
xposure to fine-particulate air pollution over as short a time frame as three years could increase your risk of developing lung cancer, according to research. The team looked at the relationship between exposure to PM2.5 air pollution and lung cancer in groups of people across England, Taiwan, South Korea and Canada. They say higher levels were associated with a higher frequency of EGFR-mutant lung cancer, triggered by the mutation of the EGFR gene. The researchers add this suggests lung tumours may develop in a two-step process; first, a gene mutates, then other factors allow these mutated cells to grow and expand into cancer.
