A few hours of daily exercise may help prevent breast cancer and also help those who are suffering to cope, said studies.
In one study, researchers surveyed 15,000 women and found that those who indulged in over six hours of strenuous exercise a week and have no family history of breast cancer may be 23 percent less likely to develop the disease than women who don't exercise at all.
Another study showed that a 12-week group exercise programme might lift moods and boost physical functioning in women with early-stage breast cancer, reported an online edition of health magazine WebMD.
The researchers, however, don't promise that exercise will prevent breast cancer completely. They don't blame breast cancer on a lack of exercise either. Many factors affect cancer risk. But, they do report that exercise appears to have benefits in protecting against cancer for women of all ages.
"We have found that exercise likely offers protection against breast cancer regardless of a woman's stage in life," researcher Brian Sprague, of the University of Wisconsin Paul P. Carbone Comprehensive Cancer Center, said in an American Association for Cancer Research (AACR) news release.
"The take-home message for women should be that it is never too late to begin exercising," said Sprague.
