Research studies have provided conflicting results regarding the possible link between flying duties and a higher incidence of testicular cancer. Most of these studies have looked exclusively at pilots or civilian aircrew. No studies to our knowledge have looked at the incidence of testicular cancer in enlisted male aircrew. A retrospective cohort study was conducted using the Automated Central Tumor Registry and Air Force Personnel Center data to determine the incidence of testicular cancer in U.S. Air Force active duty (AFAD) enlisted male aircrew and nonaircrew from 1998 to 2008. There were 13 AFAD enlisted male aircrew and 187 AFAD enlisted male nonaircrew diagnosed with testicular cancer. The sample of AFAD enlisted male nonaircrew had an incidence rate of 7.8 per 100,000, and the sample of AFAD enlisted male aircrew had an incidence rate of 16.6 per 100,000. The odds ratio (2.12) suggested that AFAD enlisted male aircrew had twice the odds of getting testicular cancer than their nonaircrew counterparts. However, a two-tailed t-test on the annual incidence rates revealed that there was no statistical significance between the testicular cancer incidence rates of male aircrew versus male nonaircrew in the AFAD enlisted sample population between 1998 and 2008.
