After reviewing published evidence, University of Missouri researchers conclude the benefits of exercise outweigh the risks for breast cancer survivors, including those who develop lymphedema, a chronic swelling that commonly occurs after breast cancer treatment. Co-author Jane Armer, professor in the University's Sinclair School of Nursing, and colleagues, write about their findings in the December 2011 issue of the Journal of Cancer Survivorship.
Armer told the media, "exercise can be beneficial and not harmful for breast cancer survivors," and patients at risk for lymphedema, a condition that affects around 3 million people in the US, can exercise if they are careful and watch what they are doing:
"Each individual should balance the pros and cons of the activity she chooses, but keep in mind that being sedentary has risks and being active is beneficial in many ways, including possibly reducing the risk of cancer recurrence," she added.
Lymphedema usually results when lymph nodes are removed or treated with radiation as part of cancer treatment. It can develop any time after treatment, and traditional thinking was that patients should avoid exercise in case it prompted development of the condition.
But Amer and colleagues found patients who exercise were at no greater risk of developing lymphedema than those who do not exercise. Furthermore, exercising once lymphedema has developed does not make it वोरसे ,
