[New strategy of breast cancer treatment]

Incidence of the patients with breast cancer has been increased continuously in Japan and it will be the top of all kinds of cancers in female by the end of this century. Early detection of the disease is very important and thus the surgical treatment such as breast conserving therapy (BCT) is much more acceptable. However BCT should be performed carefully and individually for each case. The new hormonal treatments and the new anti-cancer agents are developed recently and powerful therapy with combination of these drugs and the others will be expected.
