The number of breast cancer survivors is predicted to increase to 3.4 million by 2015 (1). In spite of suggestive evidence from observational studies, randomized controlled trials have provided no convincing evidence that changing dietary patterns following a diagnosis of breast cancer can impact prognosis (2,3). However, the effects of dietary intake on breast cancer recurrence may be limited to subpopulations defined by prognostic profile, molecular subtype, or exposures to treatment.
