1. Introduction to In Situ Neoplasms In situ ductal and lobular neoplasms are non-invasive cellular proliferations confined strictly within the milk ducts and lobules of the breast. The term “in situ” translates to “in its original place,” signifying a critical biological boundary. While the cells comprising these neoplasms exhibit abnormal, malignant features under a microscope, … Read more
1. Introduction to Ductal Carcinoma In Situ Ductal carcinoma in situ is a non-invasive condition characterizing the earliest identifiable stage of breast malignancy. The terminology specifically dictates the anatomical boundaries of the disease: malignant epithelial cells are proliferating uncontrollably, but they remain strictly confined “in situ,” meaning in their original place within the milk ducts … Read more
1. Introduction In the evaluation of breast imaging, the spatial distribution of microcalcifications provides profound insight into the underlying tissue architecture and pathology. A linear calcification distribution is a highly specific radiological descriptor used when calcium deposits are arranged in a line or form a branching pattern. This linear arrangement is not a random occurrence; … Read more
