A groundbreaking Spanish study reveals that excess body fat may contribute to a staggering 40% of hormone-positive breast cancer cases in postmenopausal women, far exceeding previous estimates.
Key Findings:
- CUN-BAE measures body fat more accurately than BMI.
- 40% of hormone-positive breast cancer cases may be attributed to excess body fat.
- BMI underestimates obesity’s impact on breast cancer risk.
Study Details:
- 1,033 postmenopausal women with breast cancer and 1,143 controls participated.
- CUN-BAE categorized body fat: <35%, 35-39.9%, 40-44.9%, and ≥45%.
- BMI classifications: <25 kg/m2, 25-29.9, 30-34.9, and ≥35.
Implications:
- More accurate body fat measures like CUN-BAE can better estimate cancer risk.
- Excess body fat significantly increases hormone-positive breast cancer risk.
- Effective prevention initiatives require precise obesity measurements.
