The purpose of this legislation is to investigate the rates of cancer and mortality among military rotary-wing pilots and aviation support personnel. The aim is to determine if these individuals experience higher rates of certain cancers compared to the general population, and to identify potential environmental or occupational hazards that may contribute to these health issues. Key provisions of the legislation include a two-phase study led by the Director of the Defense Health Agency, in collaboration with the National Institutes of Health and the National Cancer Institute.
