An investigation conducted in the Swedish glass industry found workers in the industry may be at an increased risk of death from lung or colon cancer. The study, which was based at the largest glassworks in Sweden, traced the cause of death of over 600 past employees. Lung cancer deaths were 1.4 to 2.4 times higher than the national or county figures. Colon cancer deaths were at approximately 2.5 times the level in the general population. The findings support those of several other reports.
