The bill, H.B. No. 1639, mandates a study on the increased incidence of cancer among female firefighters in Texas, to be conducted by the Department of State Health Services in collaboration with the Texas Commission on Fire Protection. The study will utilize data from the cancer registry and other readily available sources to compare cancer rates, particularly focusing on cancers that affect women, such as ovarian and breast cancer.

The findings of the study are required to be compiled into a written report and submitted to the legislature by September 1, 2026. Additionally, the report must be made publicly accessible on the respective websites of the involved agencies and the cancer registry. The bill is set to take effect on September 1, 2025, and will expire on September 1, 2027.
