TESTICULAR CANCER ASSOCIATED WITH EMPLOYMENT IN AGRICULTURE AND OIL AND NATURAL GAS EXTRACTION

Abstract

A hospital-based case-control study, involving review of the medical records of 347 patients with histologically confirmed germ-cell tumours of the testis and 347 randomly selected controls with other disorders, demonstrated a significant association between this cancer and work in the agricultural industry. The odds ratio for present farming occupation was 6·27 (95% confidence limits 1·83, 21·49; p<0·05). Work in the crude petroleum and natural gas extraction industry also conferred excess risk for this cancer (odds ratio 2·29; CL 1·03, 5·11). © 1984.
