2.Exercise at least three times a week (more often is even better)

每周至少运动三次（次数越多越好）

And when you do exercise, work to keep your heart rate above its baseline level for a minimum of 20 continuous minutes. Long walks are nice too, but it's the more vigorous exercise (expect to sweat!) that really helps your heart and cuts your cancer risk.

在做运动的时候，要努力保持至少20分钟的持续运动时间让心率高于基本水平。长距离步行当然也很好，但是更加激烈的运动（最好能出汗）才能对心脏有好处并减少癌症风险。

3.Maintain your body weight, or lose weight if you're overweight

保持体重，身体要是超重了记得减肥

Research shows that being overweight or obese (especially if you're past menopause) increases your risk, especially if you put on the weight as an adult. And a study released in March 2008 by researchers at the University of Texas M.D. Anderson Cancer Center in Houston showed that obese and overweight women also had lower breast cancer survival rates and a greater chance of more aggressive disease than average-weight or underweight women.

研究表明超重或肥胖症（尤其是对于绝经期的女性而言）会增加得乳腺癌的风险，特别是当你作为成年人体重增加的时候。位于休斯顿的德州大学安德森癌症研究中心在2008年3月发布一项研究表明，肥胖和超重的女性与正常体重或体重偏轻的女性相比，得乳腺癌后存活下来的几率更小，而得更严重的病症的几率要更大一些。
