Treatment advice varies for DCIS


he best way to treat — or not to treat — a possible precursor to breast cancer has women considering their options while experts offer conflicting advice. A new review published in the journal JAMA Oncology stresses that the best care is to actively treat ductal carcinoma in situ, also known as DCIS. DCIS occurs when abnormal cells are confined to the milk ducts in the breast. Often called “pre-cancer” or “stage zero” cancer, the most accurate term is simply DCIS, said Cleveland Clinic radiation oncologist Dr. Chirag Shah. “Pre-cancer is a misleading term. Stage zero can refer to other things such as LCIS (lobular carcinoma in situ). It’s best to simply call it DCIS,” he said.

Society for Reproductive Medicine. During a normal menstrual cycle, estrogen levels reach 300. During IVF estrogen levels reach 3,000 – 10 times as high. During pregnancy, estrogen levels hit 30,000, 10 times higher than IVF and 100 times more than a normal menstrual cycle, he said. “We know pregnancy doesn’t increase risk for breast cancer. In fact it can lower risk. The brief increase of hormone levels during IVF is not thought to have an effect” on increasing risk of breast cancer, Paulson said. “It’s not Earth-shattering news,” Paulson said. “Previous studies indicated the same thing, but it confirms what we have thought: Ovary stimulation (during IVF) does not increase the risk of breast cancer.” The study by researchers at the Netherlands Cancer Institute in Amsterdam was published in JAMA.
