Capitol Hill Revives Discussion on Cancer Rates Among Aviators and Missileers
The Aviators Cancer Examination Study (ACES) Act, a bipartisan legislation aimed at investigating cancer risks among military aircrew, has been passed by Congress. The Act, which was introduced by Rep. August Pfluger (R-Texas) and co-sponsored by Rep. Jimmy Panetta (D-Calif.), Sen. Mark Kelly (D-Ariz.), and Sen. Tom Cotton (R-Ark.), is now awaiting President Donald Trump's signature [1][2][4].
The ACES Act covers pilots, navigators, weapons system operators, aircraft system operators, loadmasters, medics, and any other crew members who regularly fly in fixed-wing aircraft. The study will focus on cancers such as prostate cancer, melanoma, non-Hodgkin lymphoma, and testicular cancer, which prior medical studies have suggested are more prevalent in aviators [2].
The legislation aims to clarify the link between military aviation service and cancer risks, potentially leading to improved safety protocols for service members routinely exposed to carcinogens during flight. Additionally, confirming these associations would help affected veterans more easily prove service connection for cancer diagnoses, which is crucial for disability benefits through the Department of Veteran Affairs [1][2].
The ACES Act was introduced in honor of Andy Shurtleff, a retired colonel who died of cancer. The study covered by the amendment to the House's annual defense policy bill will be conducted by the National Academies and is due 18 months after the bill becomes law [3].
Recent studies have found that aircrews are up to 24 percent more likely to be diagnosed with cancer than the comparable U.S. civilian population [1][5]. These findings, along with personal losses experienced by lawmakers such as Col. Shurtleff, have driven the push for the ACES Act.
The Military Aviator Coalition for Health, an advocacy group, has touted both studies. Meanwhile, at least 180 current and former British military aircrews are looking to sue the Ministry of Defence for damages related to cancer diagnoses they argue stem from years of breathing toxic helicopter fumes [6].
In addition to the ACES Act, another study, the Rotary-wing Operator Toxic Occupational Research (ROTOR) Act, may soon be launched to study cancer in the rotary-wing community [7]. The Air Force is currently conducting a multipart study of whether the nuclear missile community is at higher risk of contracting non-Hodgkin's lymphoma and 13 other cancers [8].
Moreover, a 2023 review of potential carcinogens at Intercontinental Ballistic Missile (ICBM) facilities recommended each launch control facility be deep cleaned [9]. The complementary provision in the Senate's version of the bill requires the Air Force to deep clean the underground crew capsules where Airmen operate ground-based nuclear weapons every five years [10].
These measures reflect renewed momentum to investigate and address cancer risks unique to military flying operations, providing hope for a safer future for military aircrews.
