"These findings will probably be surprising to many doctors and patients alike, as BMI is the current standard method to assess the risks for diseases related to body weight," co-author Andrew Dannenberg said in a statement. "We hope that our findings will alert women to the possibility of increased breast cancer risk related to body fat, even if they have a healthy weight."
Scientists did note they were unable to determine how body fat related to the possibility of breast cancer over time and that their investigations were limited to just to postmenopausal women and not other populations or cancers. However, they believe their results are groundbreaking.
"Our findings,” co-author Neil Iyengar said, “show that the risk of invasive breast cancer is increased in postmenopausal women with normal BMI and higher levels of body fat, meaning that a large proportion of the population has an unrecognized risk of developing cancer."
