RF Radiation, Cancer and HCL Epidemiology

Here's an interesting article from the Amateur Radio Relay League (ARRL) that discusses RF Radiation Safety and studies that address the association between high-level RF Radiation exposure and cancer:

Here's an excerpt from a study of the epidemiology of Hairy Cell Leukemia:

HCL risk was concentrated in white males; there were few black and Asian patients for analysis. Overall, the age-adjusted incidence rate of HCL for men (2.9/million population) was 4.8 times greater than that for women (0.6/million population). Using data from all cancer patients diagnosed during the study period, Jewish men had significantly greater risk of HCL than Protestant men.

For men, the OR was significantly elevated for professional and technical workers (OR = 2.1, P = 0.001); within this category of occupations, risk was significantly elevated for engineers (OR = 4.0, P = 0.0008). HCL patients were more than twice as likely to have multiple primary cancer diagnoses as other cancer patients. Since the majority of the other primary cancer diagnoses occurred prior to (>1 year) or concurrent with (1 year) the HCL diagnosis, this greater frequency of multiple primaries in HCL patients may be due to impaired immune function.
