It is a study of reasonable quality, with appropriate follow-up.
There is growing evidence that lifestyle factors such as exercise, alcohol consumption, diet and overweight influence the outcome of women with operable breast cancer. This study adds information along the same lines.
It is in the range of what is achieved with the usual therapies (chemotherapy, endocrine therapy, target therapy), which is considered clinically relevant and socially important, given that every year more than two million women are diagnosed with breast cancer worldwide (35,000 in Spain). Given that the effects of treatment and lifestyle add up, the overall improvement is already significant. Moreover, adhering to these recommendations not only generates benefits in relation to breast cancer, but could reduce the risk of other tumours (such as uterine and colon-rectum) and positively affect cardiopulmonary and metabolic health.
