Obesity has long been recognized as a major risk factor for breast cancer. However, new research suggests its impact may be far greater than previously thought.
A recent study reveals that excess body fat may be responsible for 40% of postmenopausal hormone-positive breast cancer cases, a common type of breast cancer. This starkly contrasts current estimates based on body mass index (BMI), which links only 1 in 10 cases to excess weight. The new study findings suggest the need to rethink the effectiveness of BMI in assessing cancer risk.
