From the study: > This study found that compared to the U.S. population after adjusting for age, sex, and race, aircrew had an 87 percent higher rate of melanoma, 39 percent higher rate of thyroid crew had an 87 percent higher rate of melanoma, 39 percent higher rate of thyroid cancer, 16 percent higher rate of prostate cancer, and a 24 percent higher rate of cancer for all sites. Ground crew members had higher incidence of cancers of brain and nervous system (by 19 percent), thyroid (by 15 percent), melanoma(by 9 percent), kidney and renal pelvis (by 9 percent), and of all sites (by 3 percent). However, aircrew and ground crew both had lower or similar cancer mortality rates for all cancer types when compared to the U.S. population. That last bit is presumably related to the VA providing free health care for any service-connected condition.
