Wendy Demark-Wahnefried, Ph.D., R.D., professor in the University of Alabama at BirminghamDepartment of Nutrition Sciences and the associate director for cancer prevention and control in the UAB Comprehensive Cancer Center, has been named the chair-elect of the Obesity and Cancer Section of the Obesity Society. Her term as chair-elect begins Nov. 6, and she will assume the chair in November of 2015.
The purpose of the Obesity and Cancer Section is to promote research, education and advocacy related to cancer, including: understanding how obesity affects etiology, prevention and management of cancer; the development of effective strategies, interventions and educational efforts that may reduce the impact of obesity on cancer risk and progression; and promote the dissemination of knowledge of the obesity-cancer relationship to the scientific community, clinicians and the public.

But the current average is only around three births a year. Read More...
