Teacup calcifications, also known as the "teacup sign," are a specific radiologic sign indicative of benign breast conditions, particularly milk of calcium within cysts. [1] These calcifications exhibit a distinctive appearance on mammography, helping radiologists in distinguishing benign entities from malignant ones.
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]
Following nearly 400 women for 18 years, one team found that atherosclerotic cardiovascular disease - clogged arteries limiting blood flow - was diagnosed in 23% of women with breast arterial ...
The estimated prevalence of fibrocystic breast changes in women over their lifetime varies widely in the literature, ranging from 30 to 60% [23] over about 50 to 60% [24] to about 60 to 75% of all women. [25] The condition is most common among women between 30 and 50 years of age. [25]
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.
In dystrophic calcification, basophilic calcium salt deposits aggregate, first in the mitochondria, then progressively throughout the cell. [citation needed] These calcifications are an indication of previous microscopic cell injury, occurring in areas of cell necrosis when activated phosphatases bind calcium ions to phospholipids in the membrane.
A new study is raising fresh questions about the value of breast cancer screening in older women, finding that those 70 and older who underwent mammograms were more apt to be diagnosed with tumors ...
Pseudoangiomatous stromal hyperplasia (also termed pseudoangiomatous stromal proliferation) is a benign breast tumor that occurs most frequently in pre-menopausal women and men with gynecomastia. It consists of interconnecting, angulated, slit-like spaces lined by slender spindle cells and surrounded by dense collagenous stroma. [ 29 ]
