Despite discernible differences between invasive lobular carcinoma and ductal carcinoma, such as the former's heightened tendency to be ER+/PR+ and its diffuse metastatic pattern versus the nodular pattern of the latter, the precise mechanistic underpinnings driving invasive lobular carcinoma's inclination towards gynecologic organs remain elusive [9]. Here, PGR is linked to breast ductal adenocarcinoma.
