WASHINGTON (Reuters) - Staying slim and fit is especially important for cancer survivors, because obesity raises the risk of cancer coming back, the American Cancer Society said in new guidelines issued on Wednesday.
"The evidence really is quite strong for the need for cancer survivors to achieve and maintain a healthful weight," Wendy Demark-Wahnefried of Duke University Medical Center, one of the report's authors, said in an interview.
The recommendations, updating advice issued in 2001 and 2003, were published in the society's "CA: A Cancer Journal for Clinicians."
The report said obesity is a well-established risk factor for some of the most common forms of cancer, including breast cancer in post-menopausal women and cancers of the colon, esophagus, liver, gallbladder, pancreas, kidney, uterus and prostate.
It also cited increasing evidence that being overweight raises the risk for recurrence and reduces likelihood of survival for many cancers.
Demark-Wahnefried said cancer survivors also face a greater risk of heart disease and diabetes, adding, "Obesity is a big risk factor for those diseases as well as second cancers."
The American Cancer Society said nearly two-thirds of U.S. cancer patients live more than five years after diagnosis, and more than 10 million Americans now alive have been diagnosed with cancer at some time in their lives.
The report said vegetarian diets can have many benefits because they tend to be low in saturated fat and high in fiber and vitamins.
"However, no direct evidence has determined whether consuming a vegetarian diet has any additional benefit for the prevention of cancer recurrence over an omnivorous diet high in vegetables, fruits, and whole grains, and low in red meats," the report stated.
The report noted that preliminary evidence indicates that for some types of cancer, one to three hours per week of exercise can cut the risk of cancer recurrence and death.

癌症幸存者要保持健康体重
WASHINGTON (Reuters) - Staying slim and fit is especially important for cancer survivors, because obesity raises the risk of cancer coming back, the American Cancer Society said in new guidelines issued on Wednesday.
华盛顿（路透社）――美国癌症协会在星期三发布的新指引上说，对于癌症幸存者来说保持健康苗条的身材是尤其重要的，因为肥胖会提高癌症复发的风险。
"The evidence really is quite strong for the need for cancer survivors to achieve and maintain a healthful weight," Wendy Demark-Wahnefried of Duke University Medical Center, one of the report's authors, said in an interview.
该指引的一位作者杜克大学医学中心的Wendy Demark-Wahnefried在一次采访中说：“有很明显的证据表明，癌症幸存者要努力使自己达到并且保持健康体重。”
The recommendations, updating advice issued in 2001 and 2003, were published in the society's "CA: A Cancer Journal for Clinicians."
这一新指引发表于该协会出版的《临床医师癌症杂志》，是对2001和2003的指引的更新。
The report said obesity is a well-established risk factor for some of the most common forms of cancer, including breast cancer in post-menopausal women and cancers of the colon, esophagus, liver, gallbladder, pancreas, kidney, uterus and prostate.
指引说肥胖对于一些最常见的肿瘤而言是一个明确的风险因素，这些肿瘤包括绝经期后的妇女的乳癌和结肠癌、食管癌、肝癌、膀胱癌、胰腺癌、肾癌、子宫癌、前列腺癌等。
It also cited increasing evidence that being overweight raises the risk for recurrence and reduces likelihood of survival for many cancers.
该指引还引用了越来越多的证据表明，超重会增加很多种癌症的复发风险，也降低患者的生存率。
Demark-Wahnefried said cancer survivors also face a greater risk of heart disease and diabetes, adding, "Obesity is a big risk factor for those diseases as well as second cancers."
Demark-Wahnefried说，癌症幸存者患有心脏病和糖尿病的机会更大，而且“肥胖是患有这些疾病，也是再发癌症的重要风险因素。”
The American Cancer Society said nearly two-thirds of U.S. cancer patients live more than five years after diagnosis, and more than 10 million Americans now alive have been diagnosed with cancer at some time in their lives.
