Women who stay highly active throughout life are less likely to develop ovarian cancer, according to a new study.
Researchers studied more than 2,100 women and found that those who exercised more than 6 hours per week were 27% less likely to develop ovarian cancer than women who exercised less than 1 hour each week.
High activity levels protected women of all ages. However, less than one quarter of the women exercised at that level.
Exercise has previously been linked to a lower risk of breast cancer
The researchers speculate that exercise may cut cancer risk by one of the following mechanisms:
Preventing obesity
Hormonal Effects of exercise
Obstetrics and Gynecology October 2000; 96 :609-14
Exercise has already been shown to reduce the risk of breast and colon cancer. It is nice to see that we can now add ovarian cancer to the list. However, reducing one's risk of cancer is not the reason people exercise. We exercise because it makes us feel better, and for most of us it helps keep our weight where it should be.
