✦ Synopsis

Abstract

Background

The incidence of testicular cancer has increased in recent decades. The aims of the present study were to elucidate whether Swedish paper and pulp mill workers had an increased incidence of testicular cancer, and to investigate whether certain occupational groups within the pulp and paper mill workforce were at increased risk.

Methods

The study was based on the Swedish Cancer Environment Register, which links the incidence of cancer for the period 1971–1990 with 1960 and 1970 National Census data on specific industries and occupations for all employed subjects in Sweden.

Results

Among maintenance workers employed both in 1960 and in 1970 in paper mills there was an increased risk for testicular cancer (standardized incidence ratio (SIR) 7.4, 95% confidence intervals (CI) 1.5–22), especially for seminomas (SIR 10.1, 95% CI 2.1–29). Maintenance workers were also at increased risk when analyzing workers employed in 1960, 1970, or both years.

Conclusions

This study indicates an increased risk for testicular cancer, especially seminomas, among maintenance workers, but not among process workers, in Swedish paper mills. Am. J. Ind. Med. 43:642–646, 2003. © 2003 Wiley‐Liss, Inc.
