Exercise May Help Thwart Ovarian Cancer | WPN World People News

Lack of exercise is associated with an increased risk of ovarian cancer and of death from the disease, two new studies suggest.

"Women may be overwhelmed with mixed messages about physical activity or exercise recommendations and opt to be inactive because they feel that they cannot meet the recommended amount of physical activity," said expert.

"Our findings suggest that any amount of regular, weekly recreational physical activity may reduce the risk for and improve survival from ovarian cancer, while a lack of regular exercise throughout adulthood is associated with an increased risk of developing and dying from ovarian cancer," expert said.

In one study, the researchers analyzed data from more than 8,300 ovarian cancer patients and more than 12,600 women without ovarian cancer. Those who said they had done no recreational physical activity during their lives were 34 percent more likely to develop ovarian cancer than those who exercised regularly, the researchers found.

The link between inactivity and a higher risk of ovarian cancer was seen in both normal-weight women and those who were overweight or obese, according to the study.

The other study of more than 6,800 ovarian cancer patients found that women who were inactive in the years before the diagnosis were 22 percent to 34 percent more likely to die of the disease than those who had done at least some regular weekly exercise. Again, this was true in both normal-weight women and those who were overweight or obese.

"While the current evidence regarding the association between different amounts of physical activity and ovarian cancer remains mixed, our findings demonstrate that chronic inactivity may be an important independent risk and prognostic factor for ovarian cancer," said expert.

Less than 45 percent of ovarian cancer patients survive five years, the researchers said in background notes.
