Exposure to Particle Radioactivity and Breast Cancer Risk in the Sister Study: A U.S.-Wide Prospective Cohort
Menée à l'aide de données de la cohorte "Sister Study" portant sur 50 884 femmes américaines âgées de 35 à 74 ans, cette étude analyse l'association entre une exposition à la radioactivité des particules ambiantes résidentielles et le risque de cancer du sein
Outdoor air pollution has been classified as a human carcinogen. The evidence for breast cancer risk is accumulating although the specific constituents driving the association are not well explored. Particulate matter can be a vector for radioactive isotopes, most of which arise from naturally occurring radon gas, which has been associated with a higher risk of breast and lung cancer. We evaluated the association between residential ambient particle radioactivity (PR), a radiometric characteristic of airborne particulate matter, and incident breast cancer.
