Dear jeana1102, The BI-RADS scale of rating mammograms is a scale from 1-5 with 1 being negative with nothing to comment on, and 5 being highly suggestive of
malignancyHyperpigmentation w/malignancy
Malignancy. A Birads 3 rating of a mammogram means "probably
benignBenign ear cyst or tumor
Benign positional vertigo finding - very high probablility of benignity. Short-term follow-up being recommended to establish stability". The decision about what to do at this time (6 month follow up or second opinion) would be what you feel most comfortable with doing.
Or you can also consider asking for a CA 15-3 or CA 27.29 blood test to see if it is above normal range. If it is, then you can think about asking for repeat imaging. (Read online about these blood tests first.)
