Mortality from scrotal cancer in metal machinists in England and Wales, 1979-80 and 1982-90.
The hazard of scrotal cancer from cutting oils was first recognized in the 1950s, and led to various control measures including the introduction of solvent refined oils, use of splash guards, provision of protective clothing and washing facilities and education of workers to encourage early detection and treatment of tumours. To assess how effective these controls have been, we have analyzed occupational mortality from scrotal cancer in England and Wales during 1979-80 and 1982-90. Over this 11-year period 85 deaths were attributed to the disease in man aged 20-74. This represents a reduction in mortality from the 1960s. Significantly elevated proportional mortality ratios (PMRs) were found in press and machine tool setters (PMR 1,678, five deaths), centre lathe turners (PMR 1,099, three deaths) and machine tool operators (PMR 303, eight deaths), but all of the metal machinists who died of scrotal cancer had been born before 1930, and could have worked with cutting oils before controls were introduced. These findings are reassuring, but continued monitoring of scrotal cancer incidence and mortality is required.
