There is a link between breast cancer and weight loss:new study

California,october 9: A new study found out that women with weight loss greater than or equal to 5 per cent had a 12 per cent lower breast cancer risk compared to women with a stable, with no interaction by body mass index. Weight gain of greater than or equal to 5 per cent was not associated with risk of breast cancer overall but was associated with a 54 per cent higher incidence of triple negative breast cancer.

Dr. Rowan Chlebowski says that "Our study indicates that moderate, relatively short-term weight reduction was associated with a statistically significant reduction in breast cancer risk for postmenopausal women."

"These are observational results, but they are also supported by randomised clinical trial evidence from the Women s Health Initiative Dietary Modification trial where, in a randomised clinical trial setting, adopting a low-fat dietary pattern that was associated with a similar magnitude of weight loss resulted in a significant improvement in breast cancer overall survival. These findings, taken together, provide strong correlative evidence that a modest weight loss program can impact breast cancer."
