• Association was seen in all women, regardless of weight.
• Exercising more than 150 minutes per week showed benefit.
• Endometrial cancer risk was reduced by 34 percent.
PHILADELPHIA — Women who exercise for 150 minutes a week or more may see a reduced risk of endometrial cancer, despite whether or not they are overweight, according to data presented at the Ninth Annual AACR Frontiers in Cancer Prevention Research Conference, held here Nov. 7-10, 2010.
“This study is consistent with other studies that strongly support the association between physical activity and lower risk of endometrial cancer,” said Hannah Arem, a doctoral student at Yale School of Public Health.
Arem and colleagues examined data collected from a case-control study led by Herbert Yu, M.D., M.Sc., Ph.D., associate professor at Yale School of Public Health. The study included 668 women with endometrial cancer and compared them to 665 age-matched control women.
Those who exercised for 150 minutes a week or more had a 34 percent reduced risk of endometrial cancer compared with those women who were inactive.
This association was more pronounced among active women with a body mass index (BMI) less than 25, or underweight women, where the reduction in risk was 73 percent compared with inactive women with a BMI more than 25, or what is commonly considered overweight.
Although BMI showed a strong association with endometrial cancer, even women who were overweight, but still active, had a 52 percent lower risk.
“Clearly, programs should be in place to increase the level of physical activity in women,” said Arem.

The mission of the American Association for Cancer Research is to prevent and cure cancer. Founded in 1907, the AACR is the world’s oldest and largest professional organization dedicated to advancing cancer research. The membership includes 32,000 basic, translational and clinical researchers; health care professionals; and cancer survivors and advocates in the United States and more than 90 other countries. The AACR marshals the full spectrum of expertise from the cancer community to accelerate progress in the prevention, diagnosis and treatment of cancer through high-quality scientific and educational programs. It funds innovative, meritorious research grants, research fellowships and career development awards. The AACR Annual Meeting attracts more than 18,000 participants who share the latest discoveries and developments in the field. Special conferences throughout the year present novel data across a wide variety of topics in cancer research, treatment and patient care. Including Cancer Discovery, the AACR publishes seven major peer-reviewed journals: Cancer Research; Clinical Cancer Research; Molecular Cancer Therapeutics; Molecular Cancer Research; Cancer Epidemiology, Biomarkers & Prevention; and Cancer Prevention Research. AACR journals represented 20 percent of the market share of total citations in 2009. The AACR also publishes CR, a magazine for cancer survivors and their families, patient advocates, physicians and scientists.
