Brief Summary

It is well known fact that postoperative whole breast radiation therapy (RT) in left breast cancer patient can cause cardiac problem according to the exposed dose. In the several studies in other countries, it was repeatedly showed that RT on prone position can reduce cardiac exposed RT dose in left breast cancer. However, the effectiveness of prone position in RT is not studied in the Korean women have relatively small breast. The investigators planned this study to evaluate the real efficacy of prone position in Korean breast cancer treated with RT.
