What is the ALPHA Trial?



Breast cancer affects thousands of women in Canada every year. Research has shown that there is a link between increased physical activity and decreased breast cancer risk. This association is true in older women, and also applies to people who only started activity late in life. However, we do not yet understand HOW activity influences breast cancer risk. The ALPHA Trial is examining how increased physical activity decreases the risk of breast cancer in postmenopausal women.

The study is one of the first in the world of its kind, and is generating valuable information on how women can decrease their own risk.

Women between the ages of 50 -74 who did not have breast cancer and who did not exercise at the time they enrolled were studied.
