Abstract
BACKGROUND: Among workers employed at a nickel refinery in Harjavalta, Finland an increased risk of lung and sinus cancer has been demonstrated in two previous studies. The current study adds 16 more years of follow-up to these studies. METHODS: A total of 1,115 persons exposed to nickel and 194 non-exposed workers in the Harjavalta nickel smelter and refinery were followed up for cancer from 1967 to 2011 through the Finnish Cancer Registry. RESULTS: The total number of cancer cases in men was 251 (Standardized incidence ratio (SIR) 1.05) and in women 12 (SIR 1.22). In the most nickel-exposed work site (refinery), there were 14 lung cancers (SIR 2.01) and 3 sinonasal cancers (SIR 26.7, 95%). CONCLUSIONS: It is likely that exposure to nickel compounds is the main reason for elevated nasal cancer risk among the nickel refinery employees and may also contribute to the excess risk of lung cancer.
