Exercise has been touted as a way to help lower a women's risk of getting breast cancer and now some new research tries to figure out how much is needed and at what age women can benefit.

A study in the journal Cancer finds women who exercised about two hours a day, five days a week, were less likely to developed breast cancer.

That's compared to less active women.

The intensity didn't seem to matter.

Moderate physical activity such as walking or cleaning house worked fine and the benefits were seen by women before and after menopause.
