Lay Description

In a small study at Johns Hopkins, women were treated with partial breast irradiation and chemotherapy given at the same time.

We are now testing in a bigger study whether giving partial breast irradiation and chemotherapy at the same time (our new method) has the same side effects and outcomes as giving partial breast irradiation and chemotherapy at different times(older method). In this study women who had their breast cancer removed but need radiation to the breast will be randomized to partial breast irradiation at the same time as chemotherapy or partial breast radiation at a different time than chemotherapy. Randomization is like flipping a coin but in this study about 2 of every 3 women will get the new method.
