Breast density, defined as the percentage of fibroglandular tissue in the breast, has the potential to be used as a predictor of breast cancer risk. Recent studies indicate that the maximum punctual breast density, which is an underexplored measure and is a factor that has a greater link with breast cancer than the global breast density, the latter is the most used to measure the breast density. This study aims to identify whether the breast point density of 1cm2 of area is located in different regions of the breast in the different compressed breast thicknesses (CBT). In this retrospective study, mammographic images were analyzed in the medial-lateral oblique (MLO) and craniocaudal (CC) projections of 1192 women aged between 25 and 89 years and CBT between 30 and 89 mm. The information used was: CBT (mm), the distances from the posterior, superior and medial edges of the breast, (DPEB) (mm), (DSEB) (mm), and (DMEB) (mm), respectively, up to the location of the 1 cm2 of the maximum breast density punctual (MBDP), the volumetric density of the global breast (VDGB) (%), the MBDP (1 cm2) and the volume of the breast (cm3). The results of this study show that MBDP follows the same behavior as VDGB, in relation to the influence of CBT. Regarding the location of the MBDP, there is little evidence that CBT is a factor of strong influence.
