Breast cancer is one of the most common malignant tumors in women. Combined treatment of traditional Chinese medicine based on Western medicine can greatly improve its prognosis. Deficiency of Yin and Yang constitutes the primary pathogenesis of breast cancer

and hence its treatment can be performed from the aspects of Yang deficiency syndrome and Yin deficiency syndrome. For patients with the Yang-deficiency breast cancer

there is a high risk of affection by exogenous pathogenic factors of wind

cold and dampness; and patients may lose the abilities of Qi-promotion and Qi-warming

leading to phlegm dampness blood stasis with time eventually. These patients may manifest the syndrome characteristics of scattered swelling

unchanged skin color

no pain or itching and systemic Yang deficiency in the early stage of the lesion. Its syndrome shares similarities with "carbuncles of Yin nature"

and it can be treated with

Yanghe

Decoction. Meanwhile

for patients with Yin-deficiency breast cancer

there is a risk of pathogenic factors invading the hepatic collaterals

which may remain in the Ying-blood and cause heat transmission over time. These patients may manifest the syndrome characteristics of high risk of local ulceration

metastasis

progression to late stage and systemic Yin deficiency. Its syndrome is similar to a "pathogen lurking in the Yin phase"

and it can be treated with

Qinghao Biejia

Decoction. Significantly

under the guidance of the theory of reinforcing Yang from Yin and reinforcing Yin from Yang and considering the disease characteristics of systemic deficiency of healthy Qi and local excess of pathogenic factors

Yanghe

Decoction and

Qinghao Biejia

Decoction can also be applied jointly

associated with external treatment.
