Risk factors of laryngeal cancer in Central and Eastern Europe
A case-control epidemiologic study in squamous-cell carcinoma of the larynx (LC) vs. smoking was carried out. Although no independent influence of drinking was found, the synergetic effect of the two habits potentiated the carcinogenic impact. Approximately 87% of LC cases are attributable to tobacco use in Central and Eastern Europe. Occupational exposure to coal dust is regarded as a possible cause.
