[Progress of Japan Mammary Cancer Society and future perspectives].

One of the important past achievements of the Japan Mammary Cancer Society was the establishment of the general rule for clinical and pathological record of mammary cancer. The past two decades have seen major changes in our understanding of the biology of the breast cancer as well as in diagnosis and management. The prediction of the future is extremely difficult. However, there is a future need to develop tests of tumor and host potential for spread. A future goal of chemotherapy selectivity would be to develop ways of testing for drug selection.
