The purpose of the ACES Act of 2025 is to investigate the rates and causes of cancer among military personnel who served as aircrew members in the Armed Forces. This legislation aims to better understand the health risks faced by these individuals due to their military service. Key provisions of the Act require the Secretary of Veterans Affairs to work with the National Academies of Sciences, Engineering, and Medicine to conduct a comprehensive study. This study will look into various factors, including exposure to harmful chemicals and other agents that may be linked to cancer.
