Exercise 'boosts breast cancer survival'

12 September 2006

Exercise could help to improve breast cancer survival rates, according to a new study.

Scientists at the University of North Carolina have published a study examining the history of 1,264 women with breast cancer. Researchers found that overweight or obese women who take part in high levels of physical activity in the year before they are diagnosed with breast cancer have an improved chance of surviving the disease.

The research, published in the October issue of the journal Cancer, concluded that there were no added survival benefits from increased exercise in women with a BMI (body mass index) of below 25.

Researchers are keen to identify factors that could influence the ability to survive cancer in order to improve treatment and disease management.

Earlier studies have indicated that body weight could predict the chances of surviving breast canceral. The authors claim that this latest research may help to establish additional factors, including physical activity, which could affect the outcome of the disease.

"Given that obesity is relatively well established as a poor prognostic factor in breast cancer, it is hopeful that activity may provide an opportunity to improve survival in this sub-population," said the authors.
