Even after adolescence starts, they may miss periods if they workout regularly. Although delayed or missing menstrual periods often is thought to be abnormal, some experts now say it is natural and even desirable, because it may protect the body from the damaging effects of sex hormones. The Associated Press Rose E. Frisch of the Harvard School of Public Health said that girls typically now have their first periods at age $12_{1/2}$. But if they exercise in such vigorous sports as tennis, running or basketball their average age at menarche is $15_{1/2}$. Frisch said the more menstrual cycles a woman has over her lifetime, the greater her chance of breast cancer, the biggest cancer-related killer among U.S. women. So anything that delays the start of menstruation should lower the cancer risk, he said. 2601 Iowa 843-3008 Jack Fishman of Rockefeller University said breast cancer may take 40 years to develop. "What you do in puberty can be very relevant to what happens in breast cancer after menopause," he said. - List for the main points * Tune out distractions * Take useful notes * Use notes for exam reviews No Charge LISTENING & NOTETAKING INTENSIVE WORKSHOP Wednesday, February 17 Wednesday, February 17 7:00-8:00 p.m. 300 Strong Hall Learn & practice skills to: 14th & Ohio, Lawrence, Kansas (Under the Wheel) ALawrence Tradition Since 1978 Presented by the Student Assistance Center 1012 Mass.
