Dear whyme00, 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.
