In the period 2006–2010, the

Nation-al Cancer Registry indicated a gradual increase in the incidence of malignant tumours among men, from 64,092 thousand in 2006 to 70,024 thousand in 2010. In the reference period, the number of deaths due to malignant tumours among men oscillated around 52 thousand. The aim of this study was to analyse the incidence of malignant tumours in the male population of Poland in the period 2006–2010. The study material comprised data ob-tained from the National Cancer Regis-try and from the Central Statistical Of-fice, available on the websites of these institutions. The malignant-tumour incidence rate among the male population in 2006– 2010 showed a slow but steady growth, while the death rate dropped slightly at the end of 2010. The hypothesis that the cancer-incidence risk grows with age has been proven, and a substantial increase in this risk is observed from the fourth decade of life. The most common malignant tumours in Poland in the an-alysed period included lung cancer, fol-lowed by prostate cancer and colorectal cancer. Future prophylactic and educational programmes should be addressed to men prior to reaching the age of in-creased cancer risk. Key words: malignant tumours, inci-dence, male population
