Researchers at The University of Texas M. D. Anderson Cancer Center have found that exercise decreases pain and helps breast cancer survivors feel healthier and increase participation in daily activities.
The Active for Life after Breast Cancer Study, published Friday in the journal, Patient Education and Counseling, evaluated the effect of exercise on former cancer patients' physical well-being.
Approximately 60 breast cancer survivors, randomly placed in a lifestyle intervention group or a standard care control group, participated in the six-month, 21-session study. Researchers taught participants to incorporate short periods of moderate exercise into their daily routines, which included 30 minutes of physical exercise at least five days per week.
According to Karen Basen-Engquist, Ph.D., principal investigator of the study and associate professor of behavioral science at M. D. Anderson Cancer Center, study leaders informed participants that they should still be able to talk while exercising at a moderate level, but they should not be able to sing during the activity. Lifestyle intervention participants met weekly for four months and then semi-weekly for two months to learn cognitive and behavioral skills to support effective behavioral change.
Study leaders emphasized that physical activity need not be an organized, lengthy endeavor, but rather a lifestyle activity that could include vacuuming, brisk walking or climbing stairs rather than taking the elevator.
"The wonderful take-away message from this study is that simple exercises, such as walking during coffee breaks or parking further away from work, can have beneficial effects on physical health and functioning," said Basen-Engquist. "Exercise doesn't need to be a daunting activity or even an organized outing to reap significant rewards for breast cancer survivors."
The study examined barriers to increasing physical activity, including time restraints, other commitments, fatigue, pain or muscle problems, incontinence, hot flashes and premature menopause due to chemotherapy.
"We found that exercise improved participants' ability to perform certain physical tasks, increased self reports of feeling healthy and decreased pain and the degree to which their activities were limited by physical health problems," said Basen-Engquist.
She notes that study leaders invited participation from a pool of breast cancer survivors who had recently completed both radiation and chemotherapy. Women who maintained primarily sedentary lifestyles were chosen as ideal candidates "because we wanted to see if through the study they would integrate exercise into their daily lives," said Basen-Engquist.
Researchers at M. D. Anderson Cancer Center partnered with the Kelsey Research Foundation, a non-profit organization dedicated to improving the quality of patient care and health outcomes through research and education; Kelsey-Seybold, a large, multi-specialty health care clinic; the Houston chapter of the Sisters' Network, a support and advocacy group for African-American breast cancer survivors; and The Rose, a Houston non-profit agency that sponsors support groups for breast cancer survivors, in recruiting study participants.
