In 2012, the Women Firefighters Biomonitoring Collaborative, led by Silent Spring Institute and UC Berkeley researchers, was founded when SFFCPF approached the United Fire Service Women and environmental health advocates with concerns about multiple cases of breast cancer among their ranks. Partially funded by SFFCPF, this resulted in the first studies of women firefighters to assess chemical exposures, including exposure to chemicals linked to breast cancer. This is the second published study as it continues to evolve.
