Could Walking Help Lower Cancer Risk?

这是一个很好的理由蕾丝步行鞋每天：regular exercise habitmay help to lower your risk of certain types of cancer. A审查医学文献显示了定期的体育锻炼，例如walking，可能有助于降低乳房，结肠，肺，子宫内膜，肾脏和前列腺癌的风险。而且，有些研究显示身体活跃的女性可能会使乳腺癌风险降低25％。

步行也已被证明对目前患有癌症以及缓解癌症的人是有益的。在整个治疗方案中行走的患者以及在完成治疗后走路的幸存者可能会经历与癌症治疗有关的短期和长期副作用，他们可能会遇到lose less muscle mass与身体不活跃的癌症患者相比。

癌症患者在飞行中与宇航员的相似学习: Both groups experience stressors that can cause long-term changes like decreased muscle mass, lowered bone density and changes in heart function. The study authors suggested cancer patients could benefit from regular exercise like walking, which has been shown to be beneficial for astronauts. NASA’s rigorous countermeasures program helps astronauts fight the decrease in muscle mass associated with time spent in space. In contrast, cancer patients are often told to rest during treatment, which can contribute to decreases in muscle mass, so people could benefit from veering from the status quo.

根据多种原因，步行与癌症风险的降低有关。丽莎·奥斯特·戈斯曼（Lisa Auster-Gussman），博士，西北大学芝加哥Feinberg医学院预防医学系的研究员和博士后研究员。“运动有助于调节雌激素等激素，雌激素与乳腺癌升高有关；它减少了慢性炎症，增加免疫功能and提高胰岛素敏感性, all of which lowers the risk of certain cancers.”

定期行走may also lead to weight loss，这与某些癌症的风险降低有关。“肥胖与许多癌症的风险增加有关，包括乳房，结肠，子宫，内分泌等。”Dr. Jorge Cortes, director of the Georgia Cancer Center at Augusta University.

Beyond preventing the loss of muscle mass and bone density, walking provides additional benefits to mental and physical health. “步行has been shownto improve energy levels and reduce fatigue in cancer patients,” says Cortes. “It can also help with stress,depression， 焦虑，insomnia以及癌症患者常见的其他症状。”

步行is an ideal form of exercise for most cancer patients who undergo chemotherapy, radiation, targeted therapy, immunotherapy or other treatments because it’s low-impact and easy. “Many patients prefer walking [because] it is not too strenuous,” says约书亚·曼苏尔博士是董事会认证的血液学家和肿瘤学家，洛杉矶市希望市癌症中心和Kaiser Permanente。“许多医院将帮助患者在住院期间，在他们在地板或单位周围完成一定数量的圈子时给他们带来奖牌或代币的住院时，甚至可以激励患者在医院中行走。患者发现这很有趣。它有助于他们下床，并多次将他们匆匆忙忙地吞噬内啡肽，并增加他们的心情。”

癌症患者也可能喜欢走路，因为他们能够决定如何或何时运动。奥斯特·古斯曼（Auster-Gussman）说：“这实际上对治疗期间的人来说确实是积极的，当他们的身体通常感到无法控制时。”

Whether you’re walking with hopes of decreasing your cancer risk or to make cancer treatments easier to endure, it may help if you move for as least as long as the体育活动指南推荐：150分钟的中等强度运动每个星期。您是否能够在给定的一周中实现此目标可能取决于您的治疗方案。

曼苏尔说：“特定的程序或实验室数据可能会阻止患者保持自己的活跃状态。”“如果能够，大多数医生每天都会推荐30分钟的步行或活动。”

一些研究表明，运动以更高的强度进行，包括brisk walking, may have the most positive effects for longevity and walking can be safer for those who are injury-prone, says Cortes. Still, he cautions that any “activities that have more risk of falls or trauma may pose more risks and should always be discussed with the healthcare team first.”

将步行纳入日常工作可能会对您的癌症状况产生积极影响。不管您能够走多少，有些人总是总比没有好。甚至just 10 minutes of walking a day可以对身心健康产生积极影响。
