Strong Medicine

Dana takes a leave from the clinic to help her mother through a double mastectomy. Lu's impromptu safe-sex speech at a prep school's career day puts her in the middle of a legal dispute over a date rape. Peter's ""alternative"" approach to pain management for a patient with Hodgkin's disease gets them both arrested. And Dana and Lu must each decide how much they want to know when they are both tested for the mutated BRCA1 and BRCA2 genes that would reveal a predisposition to breast cancer.
