The invention relates to a method for taking the breast cancer molecular marker S100A8/A9 in diagnosis and prognosis evaluation of the breast cancer. According to the method, results show that the expression indexes of the molecular marker S100A8/A9 in breast cancer patients with different molecular pathological subtypes are different, that is, thesubtypemolecular marker S100A8/A9 is highly expressed in a substrate cellular type (basal-like) breast cancer patient and a Her-2 amplified) overexpression type breast cancer patient, but is relatively low in expression index in a lumen epithelia A type (Luminal A) breast cancer patient and a lumen epithelia B type (Luminal B) subtype breast cancer patient, that is, the statistic difference is obvious.
