The epidemiological risk factors of the larynx cancer among the native and migrant male population.
In the present paper relative risk of larynx cancer has been evaluated in 272 cases in the stationary (native Upper Silesians) (65.4%) and migrant (34.6%) population of men. The corresponding control groups (total 739 men) consisted of 401 (54.3%) and 338 (45.7%) men, respectively, who did not suffer from neoplastic diseases. The important relationship between larynx cancer incidence and cigarette (with or without filter), pipe and cigar smoking has been proved. It has also been shown that the evaluation of larynx cancer risk according to the birth place of populations is more useful, because it enables to discover new epidemiological aspects of the larynx cancer. The higher larynx cancer risk has also been disclosed in men who are in manual work, and who are immediately exposed to the influence of various dusts and gases in their place of work. It has been discovered, that chronic inflammation of the upper respiratory tract, pneumonia, tuberculosis, emphysema or bronchitis also influence higher larynx cancer incidence risk in the native and migrant populations analysed.
