[The assessment of age-standardised cancer incidence rates in the chosen organ systems].

Age-standardised cancer incidence rates in reproductive system, digestive system and respiratory system were analyzed taking into account the statistics for 38 States of USA (1996-2001), European Union (2006) and Europe (2006). Age-standardized incidence rate in the reproductive system was higher in comparison with the corresponding rates for digestive and respiratory systems. The authors put under discussion a hypothesis of this phenomenon.
