In classical traditional Chinese medical literature, breast cancer is called "Ru Yan," or "breast stone." Chinese medicine believes that the fundamental cause of breast cancer is emotional disturbances such as excessive thinking or anger, which lead to functional disorders of the Liver and Spleen. A common causative pattern is that excessive Heat from a deficient Liver, combined with Phlegm Dampness due to Spleen dysfunction, results in the blockage of Chi and Blood, which then "condenses" into breast cancer. Another common causative pattern is when Liver Deficiency and Kidney Deficiency lead to Chi and Blood Deficiency. Chronic Chi and Blood deficiency then leads to Qi Stagnation and Blood Stasis, which causes the formation of lumps in the breast. A third pattern is when Qi Stagnation and Phlegm accumulation lead to excessive Heat toxins, which then turn to hard breast lump masses.
Breast cancer was believed to be one of the "four fatal diseases" in traditional Chinese medicine before the modern surgical operations, chemotherapy, and radiation therapy were invented. The condition of "breast stone" was diagnosed and treated, of course, with traditional surgery, acupuncture, and herbal formulas, but the results were often disappointing. However, the Chinese tradition of close observation and painstaking collation of symptoms and cures provides us with extensive information on the diagnosis and treatment of breast cancer. Traditionally, four patterns of breast cancer are differentiated and treated: Liver Qi Stagnation (hard masses without pain and redness); Phlegm Heat Obstruction (hard masses with sharp pain and redness and swelling); Liver Kidney Deficiency (hard lumps with swelling and a dimpled appearance of the breast skin, discharges and indentation of the nipple); Qi Blood Deficiency (hard lumps with swelling, ruptured abscesses, spreading to the surrounding areas).
