US HB4704

Directs the Defense Health Agency, coordinating with NIH and the National Cancer Institute, to conduct a two-phase study on cancer prevalence and mortality among military rotary-wing pilots and aviation support personnel who served on or after February 28, 1961

Initial phase must examine 12 specific cancers (brain, breast, colon/rectal, kidney, lung, melanoma, non-Hodgkin's lymphoma, ovarian, pancreatic, prostate, testicular, and urinary bladder) and compare rates to the general population, with a report due within one year of enactment

Second phase, triggered if elevated cancer rates are found, would identify carcinogenic toxins from aircraft operation (fumes, fuels), non-ionizing radiation exposure from radars, and other military service exposures such as burn pits and contaminated water

Study data must be formatted consistent with the Surveillance, Epidemiology, and End Results (SEER) program and disaggregated by race, gender, and age

Reports must be submitted to the Armed Services and Veterans' Affairs Committees of both the House and Senate
