When horizontal x-ray beams, commonly used in lateral projections, are used to image the breast, the fluid inside the cysts, such as milk of calcium, is imaged tangentially. [2] This technique often produces linear or curvilinear patterns of calcification. In some cases, a semilunar shape may appear, which is why this sign is called "teacup sign."

Stereotactic biopsy, also known as stereotactic core biopsy, is a biopsy procedure that uses a computer and imaging performed in at least two planes to localize a target lesion (such as a tumor or microcalcifications in the breast) in three-dimensional space and guide the removal of tissue for examination by a pathologist under a microscope.
When consisting of calcium phosphate, they are usually dystrophic calcifications (occurring in degenerated or necrotic tissue). [3] Yet, the mechanism of their formation is not fully known. [4] Calcium oxalate crystals in the breast may be seen on mammography and are usually benign, but can be associated with lobular carcinoma in situ. [5]
Affected ducts have characteristic necrotic tissue which is composed of multiple, well-defined firm masses of dead cells. In most cases of comedocarcinomas (approximately 78%), [6] mammograms will reveal micro-calcifications in the breast tissue due to the calcification of necrotic elements. Upon physical examination, the infected area can ...

Atypical ductal hyperplasia (ADH) is the term used for a benign lesion of the breast that indicates an increased risk of breast cancer. [1]The name of the entity is descriptive of the lesion; ADH is characterized by cellular proliferation (hyperplasia) within one or two breast ducts and (histomorphologic) architectural abnormalities, i.e. the cells are arranged in an abnormal or atypical way ...
Dystrophic calcification (DC) is the calcification occurring in degenerated or necrotic tissue, as in hyalinized scars, degenerated foci in leiomyomas, and caseous nodules. This occurs as a reaction to tissue damage, [ 1 ] including as a consequence of medical device implantation.
