Narrator: This is Science Today. Heart disease is still the number one killer of both men and women, but when it comes to the disease women in particular fear most, breast cancer tops the list. Dr. Rita Redberg of the University of California, San Francisco says while this is easy to understand, she worries women may not be as diligent about protecting their hearts.
Redberg: Women are much more likely to die of heart disease. In fact, one in three women will die of cardiovascular disease in this country. Where it's about one in nine for breast cancer which is commonly what women will cite as their biggest health fear.
Narrator: Because heart disease is largely preventable, Redberg says understanding your risk is of upmost importance.
Redberg: Because there are a lot of things that people can do to prevent heart disease but if you're not thinking that heart disease is going to be an issue for you, then you're not as likely to engage in preventative type behavior. And unfortunately it's true for most of us that heart disease will be an issue.
