A research team from the University of Florida has revealed in a recent study that women living in areas with high air pollution face an increased risk of developing breast cancer.
The study, which included over 280,000 women, found that exposure to fine particles emitted from vehicle exhaust is associated with higher breast tissue density — a well-known factor that significantly raises the risk of cancer. Women with dense breast tissue may face up to six times greater risk of developing the disease.
This is the first study to establish such a strong connection between air pollution and breast tissue density, with a particular focus on fine diesel particles. These pollutants are already linked to asthma, heart disease, and dementia, and are now also associated with a heightened risk of breast cancer.
Estimates suggest that air pollution contributes to around 40,000 deaths annually in the UK, and it may also play a role in some of the 11,400 annual breast cancer-related deaths. These findings open new avenues for understanding the environmental impact on women’s health.
