Īge-adjusted incidence of some but not all cancers differs between the U.S. Since 1995, cancers diagnosed in the former have been archived in the Defense Medical Surveillance System, while those diagnosed in the latter have been archived in the Veterans Administration Central Cancer Registry both systems feature stringent quality-control measures and have been used extensively for epidemiological research. After being discharged from service, eligible members may also receive care through the U.S. Active duty personnel are entitled to medical care through TRICARE, the insurance program for the U.S. Air Force has approximately 333,000 active duty personnel, of whom nearly 4 percent are pilots. Air Force fighter pilots and their officer colleagues, and to establish whether their cancer risks differ. The objective of this retrospective cohort study was to determine the incidence rate of malignancy-overall and by anatomic site-among active component U.S. In light of these discrepancies, the current study was commissioned to provide an accurate health risk assessment for U.S. Epidemiologic investigations evaluating the relationship between aviation and cancer in both military and commercial settings have yielded conflicting results: Some studies found no difference in all-site cancer rates between aviators and non-aviators, one found a higher rate among aviators, and one found a lower rate among aviators. Military aircrew personnel may experience occupational exposure to galactic cosmic radiation, ultraviolet radiation, and non-ionizing intra-cockpit radiation, leading some to speculate about an increased risk of malignancy.
