Quality Of Life During, After Cancer Could Improve With Exercise
Exercise may improve quality of life for people with cancer, according to Cochrane researchers. In two separate Cochrane systematic reviews, the authors gathered together evidence showing that activities such as walking and cycling can benefit those who are undergoing or have completed treatment for cancer.
People with cancer suffer from many different physical, psychological and social effects related to cancer, as well as treatment-related symptoms. There has been much interest in the effects of exercise on physical and psychological well-being in people with cancer. However, no previous systematic reviews have comprehensively examined the potential benefits of exercise on health-related quality of life, or on treatment-related symptoms. Cancer treatments and survival rates continue to improve, but quality of life remains a priority for people with cancer who are undergoing or have completed treatment.
"Together, these reviews suggest that exercise may provide quality of life benefits for people who are undergoing or have undergone treatment for cancer," said lead author Shiraz I. Mishra of the Prevention Research Center at the University of New Mexico in Albuquerque, US.
"However, we need to treat these findings with caution because the trials we included looked at many different kinds of exercise programs, which varied by type of exercise, length of the program and how hard the participants had to exercise. We need to understand from future trials how to maintain the positive impacts of exercise in the longer term and whether there are particular types of exercise that are suited to particular types of cancer."
