Breast conservation radiation therapy technique for women with large breasts.

A technique is presented for the conservative irradiation of women with huge (size "EE") breasts. Patients are treated in a modified lateral decubitus position with an immobilization device. The technique is easily reproducible and allows favorable cosmetic outcome. The isodose plots for treatment with this technique are compared to treatment in standard fashion. We feel that this reproducible technique offers breast conserving therapy to women with large breasts, without poor cosmesis.
