Women who practice regular physical exercise may have a reduced risk for the development of ovarian cancer, according to survey data.

Ovarian cancer is the seventh most common cancer in women in the U.S. and the fifth leading cause of cancer deaths in women. Ovarian cancer, like all cancers, results from the uncontrolled growth of a subpopulation of cells within the organ. Ovarian cancer most commonly arises from the lining (epithelial) cells on the surface of the ovary, but cancers derived from the supporting tissue (stroma) and the egg-producing germ cells can also occur. Ovarian cancer frequently has no symptoms until the cancer has spread extensively.

Doctors examined patient survey responses from over 400 women with ovarian cancer and over 2,100 healthy women who were participants in the Canadian National Enhanced Cancer Surveillance System (NECSS) to study the role of physical activity and the risk of developing ovarian cancer. The study showed that women who reported moderate levels of recreational physical activity (but not vigorous activity) or who held jobs that required moderate or strenuous physical activity had a reduced risk for development of ovarian cancer when compared to sedentary women.
