Benign Breast Lumps (Fibrocystic Changes)
Overview
Benign breast lumps, often fibrocystic changes, are common among women of reproductive and premenopausal age; both breasts may show diffuse nodules, cords, or tenderness that fluctuates with the menstrual cycle, usually worsening before menstruation and easing afterward. Chinese medicine names this 'ru pi' and attributes it mainly to liver qi stagnation with congealed phlegm, or to disharmony of the chong and ren vessels; clinical breast examination and imaging remain necessary to exclude other disease.
TCM disease & pathogenesis
This is the TCM condition ru pi (lump in the breast). The breast is traversed by the foot-yangming stomach meridian and governed in distribution by the foot-jueyin liver meridian, so the condition involves the liver, spleen, stomach, and the chong and ren vessels—the nipple belongs to liver and the breast to stomach. Frustration and anger constrain liver qi; its transverse overacting impairs the spleen-stomach, which generates dampness and phlegm. Qi stagnation carrying phlegm congeals in the breast vessels, forming lumps and premenstrual distending pain. Long-standing cases add blood stasis or chong-ren disharmony with liver-kidney insufficiency, so lumps wax and wane with the cycle. Treatment soothes liver qi, resolves phlegm, and scatters nodulation, while regulating chong-ren and quickening blood; clinical breast examination and imaging remain essential.
Pattern differentiation (clinical patterns)
Liver Stagnation with Congealed Phlegm
Breast distending or migrating pain worse before menstruation, lumps that change with mood, chest and hypochondriac fullness, low mood, thin white coating, wiry pulse.
Soothe the liver and relieve stagnation; dissolve phlegm and scatter nodulation.
Disharmony of Chong and Ren
Breast lumps with distending pain most marked before and eased after menstruation, irregular periods, sore weak lower back and knees, fatigue, pale tongue with white coating, deep fine pulse.
Regulate the chong and ren vessels; warm yang and dissolve phlegm.

Daily care & prevention
Track changes in relation to the menstrual cycle and perform breast awareness after each period; reduce stress, sleep regularly, limit caffeine and high-fat food, and wear a well-fitting bra. Press Taichong (LR3), Neiguan (PC6), Zusanli (ST36), Sanyinjiao (SP6), Jianjing (GB21), and Ganshu (BL18). Any new, hard, fixed lump must be examined.
When to seek medical care
Seek urgent breast-specialist assessment for a hard fixed irregular lump, skin dimpling or orange-peel change, nipple retraction or bloody discharge, a newly inverted nipple, or a persistent painless enlarging lump or swollen armpit nodes.
