From the TCM perspective: Breast distension: liver qi stagnation along the breast channel
Overview
Cyclical breast tenderness and swelling commonly precede menstruation or occur in pregnancy/lactation. TCM most often attributes it to liver qi stagnation in the channel traversing the breast, worse with stress/anger, or damp-phlegm/heat when lumps and redness occur. Any new lump or bloody discharge needs medical evaluation.
