Despite the unfavourable epidemiological status, the Hungarian breast cancer control is a non-appropriately developed system having considerable geographical inequalities. The study objective was to describe the small-area pattern of breast cancer mortality and of frequency of mammographical examination. The influence of socio-economical status on these patterns was also studied. The standardised mortality ratios and the standardised relative frequency of mammography was determined for settlements, zip code areas and small regions. Their correlations were analysed with education, unemployment ratio, ratio of Gypsy and German ethnic minorities, population size, smoking, distance to the nearest hospital. The South-Transdanubian Region (STR, consisting of three counties, 22 small regions, 444 zip code areas and 643 settlements) with 1 million inhabitants was the study area. All the studied parameters had significant spatial variability at all levels of aggregation. Beyond the relatively low average mortality risk in the STR, mortality clusters and increasing time trend were identified in certain areas. The mortality and the usage of mammography were inversely correlated with the indices of deprivation. These factors explain 64.5 and 17.5% of the whole variability of local mortality risks at the level of settlements and small regions. The explanatory role of these factors was similarly high for usage of mammography as well (40.2 and 52.6% for small regions and zip code areas). The factors having the strongest influence were the population size (in settlement level mortality model), ratio of gypsies (in small region level mortality and mammography usage models) and ratio of Germans (in mammography usage model for zip code areas). Inserting the counties' approaches for screening organisation into the model, it revealed that the population based screening organisation applied in Tolna county has the highest influence being 4.4 times stronger than the most important socio-economic factors. Altogether, it seems that the monitoring of spatial inequalities could improve the performance of breast cancer control identifying the populations with special needs, and there is a need to explore the pathways by which the socio-economic factors can exert their profound influence on the epidemiological status. Moreover, since the results clearly demonstrated that it is possible to achieve relatively high screening participation rates in Hungarian economical and legislative circumstances, the application of this successful method should be encouraged in other areas with low performance screening system.
