Human subjects (n=~127,800 +/- 9620 per year over a 15 year study period) serving in the Polish military during 1971-1985 were assessed for cancer incidence in association with microwave exposure history (most of which was to PW microwaves at 150 MHz to 3,500-MHz). The incidence of oral, pharynx, esophagus and stomach, colon/rectum, liver/pancreas, larynx/lung, bones, skin including melanoma, kidney and prostate, brain and nervous system, thyroid, and hematopoietic and lymphatic cancers were assessed. Exposure of 80-85% of the service posts did not exceed 0.2 mW/cm2. The remaining service posts experienced exposure intensities of 0.2-0.6 mW/cm2. The study reported an increase in overall cancer incidence rate with increased microwave exposure (OR 2.07, CI 1.1-3.6, p<0.05). Also increased were brain and CNS tumors (OR 1.91, 95% CI 1.1 - 3.5), hematopoietic malignancy incidence (OR 6.31, p<0.001, 95% CI 3.1-14.3), and esophageal and stomach cancer (OR 3.24), colorectal cancer (OR 3.19). When analyzed by age, all cancer morbidity was significantly increased in all age groups except in 50 to 59-yr olds with increased microwave exposure. The 1999 article reports results on the military population for the 20 year period from 1971-1990. For all neoplasms, the ratio for exposed to non-exposed groups was 1.83. Significantly higher morbidity rates in the RF-exposed group were noted for cancers of the alimentary tract (1.76-1.92), skin tumors (2.07), nervous system/brain neoplasms (2.7) and hematologic/lymphatic malignancies (5.33). |
