ABSTRACT
The incidence of leukaemia was compared in various provinces of Lower Silesia in the years 1972-1985. The highest incidence was in the Province of Wroclaw and the Province of Jelenia Góra, in the Province of Legnica it was lower and the lowest was found in the Province of Walbrzych. A similar sequence of the incidence was found when the analysis was carried out in groups of sex and place of residence (villages and towns). The analysis according to disease entities showed that the incidence of acute myeloid leukaemia was in the Province of Jelenia Góra, where the disease was more common in females. The authors think that the concentration and development of industry may be the cause of differences in the incidence of these diseases in various provinces of Lower Silesia.
