HIS NEWSLETTER focuses on BWHS studies of "stressors"-experiences that may evoke a stress response in the body. This "fight or flight response" has probably been Tpresent for thousands of years; for early humans, it was critical to survival. In the face of danger, the body produces chemicals that increase heart beat and blood flow, preparing the person to fight or to run away. This kind of response to short-term stress makes sense, even now. When we shout, "Don't touch!" to a toddler who is near a hot stove, the child may become stressed for a few moments, but learns not to touch the stove. However, stresses that are present IN EMERGENCY BREAK GLASS all or most of the time-chronic stresses-can have undesirable effects on physical and . The I FIGHT I IFLIGHT I BWHS is making important contributions by studying stressors in relation to a range of diseases that affect black women. This research will help explain how and why illness occurs and, we hope, provide strong evi­ ct~ dence for public policies, programs, and laws that can help reduce stress in people's lives.

THE 2013 HEALTH INFORMATION UPDATE Once again, it's time to update your health information with the BWHS. You may have received an email inviting you to fill out the 2013 health survey online, or a paper survey in the mail. Just think-your 20 minutes or so every two years has made more than 120 scientific papers possible from the BWHS, the most recent of which include results on , sarcoidosis, weight change, and uterine fibroids (check them out at www.bu.edu/bwhs). Your he lp is crucial and very much appreciated by the National Institutes of Health (which funds the study); by the doctors and health practitioners who learn from the results; by the BWHS investigators and staff; and by future genera­ tions of black women who will benefit from the findings.

ENDOMETRIAL CANCER The BWHS is leading an analysis of risk factors for endometrial cancer (cancer of the womb) in black women. The analysis is based on BWHS data and data from 10 other studies. Endometrial cancer is relatively rare and combining information from several studies provides large enough numbers of women affected with the diagnosis for clear results. PANCREATIC CANCER The BWHS is also leading an analysis of body size and pancreatic cancer in black women and men, based on data from the BWHS and five other large studies. This cancer, while rare, is an important cause of cancer death in African Americans, among whom it occurs more commonly than other ethnic groups, for unknown reasons. Because the cancer is often diagnosed at a late stage, pancreatic cancer survival rates are poor. BREAST CANCER Almost 2,000 women in the BWHS have been diagnosed with breast cancer, the most commonly occurring cancer in American women. New BWHS research will focus on factors that increase the chance of a longer, healthier life following diagno­ sis. Among the factors to be studied are dietary patterns, exercise, support from friends and fa mily, and prayer and spir ituality.
