A brief look to Figure 9, Figure 10, Figure 11, Figure 12 denotes how different breast and tumor characteristics influence breast deformations after BCS and respective wound healing process. Breast density and tumor size have particular impact on the magnitude of the displacements, while the quadrant where the tumor is positioned and the breast laterality influences the distribution of those displacement. Therefore, one can expect that breast deformations can be modelled using the spatial coordinates of points, the distance of each point to the tumor position (the distance from a point perpendicular to the tumor cylinder), while accounting for categorical features such as breast density, tumor region, breast laterality and tumor size, as described in Table 4. Despite being appointed as an important clinical factor influencing the aesthetics of breasts after BCS, the volume of the breast is not explicitly listed. However, that information is implicitly covered due to the categorization of tumor sizes (expected excision volumes) which are defined as a percentage of the breast volume.
