California Teachers Study (CTS)
Analysis of flame retardants and other persistent chemicals in blood samples for a study of women with and without breast cancer
The California Teachers Study (CTS) is a large, multi-institutional, statewide cohort study conducted by the Cancer Prevention Institute of California, the City of Hope, the University of Southern California, and the University of California Irvine to study factors influencing women’s health among active and retired female school teachers and administrators in California.
In a sub-study focusing on links between chemical exposures and breast cancer, Biomonitoring California laboratories are analyzing perfluorochemicals (PFCs), polybrominated diphenyl ethers (PBDEs), and other persistent organic pollutants (polychlorinated biphenyls [PCBs] and organochlorine pesticides) in serum samples from more than 2,500 women, half of whom have been diagnosed with breast cancer.
