I understand your concern. The tissues of the breast responds to fluctuations in the female hormone levels that waxes and wanes throughout the menstrual cycle. There can be breast pain, as well as lumps that heightens usually before the start of menstruation. The pain, lumps or swelling would usually regress once menses ensue.
I agree that you need a mammogram just to be sure that there is nothing pathologic and I also agree with the OB GYNE that this can be hormonal.
Regards and God bless.
