[Established and new surgical procedures in the therapy of breast cancer]

The established surgical procedure in the treatment of mammary cancer today is, without any doubt the modified radical mastectomy (Patey, Dyson). The adjuvant radiation therapy, following modified radical mastectomy, could not improve the all over survival of mammary cancer patients. Within the last years the breast conserving surgical procedures went more and more into the field of interest, especially of the patients. That is the reason, why these treatment-schedules should be considered very carefully according to thorough oncological principles. The radiation therapy within the conserving treatment is necessary as primary treatment in addition to surgery.
