Outdoor Air Pollution Exposure and Ovarian Cancer Incidence in a United States–Wide Prospective Cohort Study
Ever increasing rates of cancer in young patients has raised the concern that this is a consequence of pollution. For the first time evidence supporting this theory in relation to ovarian cancer is available.
Pollution presents mainly in two forms: particulate material such as micro plastics and sulphur, or gaseous such as nitrous dioxide and ozone. Using information from the” Sisters”study, which enrolled more than 50,000 women who had at least one sister with a history of breast cancer, it was possible to show how rates of ovarian cancer varied in relation to different geographic areas, with different pollution levels.
Results from this prospective analysis showed a positive association with increased nitrous dioxide levels but no association with particulate pollution or increased ozone. Nitrous dioxide is found in the atmosphere as the result of combustion mostly from fossil-fuelled transport or internal heating. Elimination of this pollutant would be a good side effect of more use of electric vehicles.
