Because industrialization in Lithuania started only about 50 years ago, occupational cancer is only now becoming an important issue. This article describes the situation of occupational cancer in Lithuania: research, exposures to carcinogens, regulation, and legal practice. Epidemiologic studies of work-related cancers have shown increased risks among cement, textile, and asbestos-cement workers. In 1997, 28% of employed workers in Lithuania were exposed to carcinogens. A legislation system regulating exposures to carcinogens, harmonized with European Directives, has recently been created. In 1995-2003, there were 5,652 new cases of occupational diseases. However, occupational cancers are seriously underdiagnosed--only one case of cancer was diagnosed as occupational. Establishment of a system that would enable diagnosis, certification, and compensation of cases of occupational neoplasms is essential in Lithuania.
