Malignant breast neoplasms are the most common cancer in women apart from non-melanoma skin cancer and thus represent a significant health burden on the Czech population. The aim of this study was to comprehensively describe the epidemiological situation of breast neoplasms in the Czech Republic with respect to the impact of organized mammary screening. The results of our analysis revealed that the greatest impact of organized screening is evident for the 45-69 age group. After the implementation of organized screening, incidence in this age group has stabilized and a significant decrease in mortality of 3.2 % each year was recorded (p < 0.001). In contrast, a significant increase of 6.8 % per year (p < 0.001) was observed for incidence of neoplasms in situ. In this age group, there was also a higher proportion of early clinical stages among newly diagnosed neoplasms in the post-screening period. Obtained results show, that after the implementation of organized mammary screening there is a positive trend of epidemiological characteristics of breast neoplasms in the Czech Republic.
