Dear jmnitsua, Microcalcifications are small calcium deposits found within the breast tissue. Microcalcifications in and of themselves are not a condition that would become cancerous however they can be a sign of a problem that may need further investigation based on their appearance on a mammogram. For instance microcalcifications that are more scattered are probably due to a
benignBenign ear cyst or tumor
Benign positional vertigo (non-cancerous) cause, a “cluster” of microcalcifications may increase concern that there may be an underlying tumor. The decision of whether or not to biopsy would be based on the appearance of the abnormality, comparisons to prior films etc. Her breast surgeon would be best able to advise regarding whether or not a biopsy was appropriate this time based on review of her films, comparisons to prior films etc.
