Breast cancer: weight loss reduces the risk in women with a BRCA1 mutation
Weight loss between 18 and 30 years 65% reduced risk of developing breast cancer in women with a mutation in the BRCA1
gene predisposing to this disease, say researchers at the conclusion of a study published in the journal "Breast Cancer Research".Steven Narod of the University of Toronto, and colleagues from other universities in Canada, the U.S. and Poland, after a thousand women, all wearing a mutation in one of two genes predisposing to breast cancer known BRCA1 and BRCA2 Fat Loss
The women were divided into two groups depending on whether they were infected or not breast cancer. After matching each other in terms of age, gene mutation carrier and the country of origin, it appears that "for women with a mutation in the BRCA1 gene, a weight loss of at least 5 kg was associated with a 65% reduction in cancer risk between 30 and 40 years. "
Conversely, women with a BRCA1 mutation who take at least 5 kg between the ages of 18 and 30 years were 44% more likely to develop breast cancer if they have two children.
The authors did, however, found no association between weight loss and the risk of breast cancer in carriers of BRCA2 mutation.
