2 nd tumors in patients treated for BREAST CANCER

 Increased lung cancer risk in breast cancer patients is largely attributed to RT  Association between RT and subsequent lung cancer was found stronger for the ipsilateral lung  Postmastectomy RT (often including supraclavicular, axillary, or internal mammary nodal region): 2 to 3-fold increased risk after 10+ years  RT after breast conserving surgery (less often including regional lymph node irradiation): impact RT is less certain

Clinical data: breast cancer
