Mammograms can detect tiny calcium deposits in the breast called calcifications 

Most are harmless, but some patterns need closer attention

There are two main types:

Macrocalcifications Large, coarse, usually benign

Microcalcifications Small, clustered, sometimes an early sign of breast changes

Regular mammograms are key:

Women 40-49: individualized screening

Women 50-74:  every 1-2 years

High-risk: individuals may need earlier or more frequent checks

Radiologists look at size, shape and arrangement

Benign patterns need no action but suspicious ones may require further tests like additional imaging or a biopsy
