Please ask your radiologist
to give a standard BIRADS score for your mammogram
.A clustered type of microcalcification is suggestive of breast malignancy.For BIRADS 3 ,you need a 6monthly mammograhy follow-up for 2 years and for BIRADS 4 , a biopsy
is indicated.In your case ,a 6 monthly mammogram seems reasonable option,with biopsy needed if there is is appearance of any mass lesion,architectural distortion of breast.
I think this standard strategy should resolve your doubts.Keep in touch.Tk care.
