HR 4704 United States House · 119th Congress

ROTOR Act

HR 4704, the ROTOR Act, requires the Defense Health Agency to study cancer rates among military helicopter pilots and aviation support personnel. It directly affects service members who served as rotary-wing aircrew (pilots or support staff) since 1961 and receive VA healthcare. The bill mandates a two-phase study: first, comparing cancer prevalence/mortality for 12 specific cancers (like lung, prostate, and breast cancer) between these service members and the general population; second, if increased rates are found, investigating potential causes like aircraft toxins, radiation exposure, or other service-related hazards. The study will use existing VA and cancer registry data, with findings reported to Congress within two years.
