Epidemiologists have identified several risk factors for breast cancer, yet clinical advice to women to change these risk factors has been uncommon. Physical activity promises to be one modifiable risk factor through which women can reduce their risk for breast cancer. Clinicians can now advise women that reducing risk for breast cancer may be one additional reason to adopt an active lifestyle. There are still questions about the type and amount of exercise needed, the ages at which exercise should be done, and the interactions with other risk factors such as reproductive and menstrual history, diet, body mass, alcohol intake, genetics, and hormone therapy. Finding answers to these questions will require a research agenda focused on the biology of exercise and breast cancer.
流行病学家已经确定了几种乳腺癌的风险因素，但向女性提供改变这些风险因素的临床建议并不常见。体育活动有望成为一种可改变的风险因素，通过它女性可以降低患乳腺癌的风险。临床医生现在可以建议女性，降低乳腺癌风险可能是采用积极生活方式的另一个理由。关于所需运动的类型和量、应该进行运动的年龄以及与其他风险因素（如生殖和月经史、饮食、体重、酒精摄入、遗传和激素治疗）的相互作用，仍然存在问题。找到这些问题的答案将需要一个专注于运动生物学和乳腺癌的研究议程。
