text_1: 55-year-old woman has had breast cancer.  Her question to me was, "What can I do to make sure I don't get ovarian cancer?"  "So screening."  I think there might be a risk of ovarian cancer in a woman with breast cancer.  I'm not sure.  Is there a role for ultrasound or CA 125 (cancer antigen 125) in this situation?
