The population of this study was all districts/cities in Indonesia conducting the screening, consisting of 4,757,732 for breast cancer screening and 603,408 for USG testing. Using the total sampling method, 508 districts/cities were included as sample with inclusion criteria having complete data. Descriptive analysis, comparative analysis using Mann-Whitney test, and correlative analysis using Spearman correlation test were performed in this study using district as analysis unit. Results of the clinical beast examination showed that there was 4.46 per 1000 (21,197 cases) lumps in the breast, and 0.16 per 1000 (738 cases) suspected of breast cancer, Meanwhile, USG test resulted in 1.11 per 1000 (672 cases) simple cysts and 1.94 per 1000 (1169 cases) non-simple cyst. There was no difference of lump in the breast, suspected breast cancer, and simple cyst between West and East of Indonesia, but there was a difference for non-simple cyst.
