New research published in the Journal of the National Cancer Institute suggests that waist circumference is a more significant risk factor for obesity-related cancers in men than BMI, based on a study of 340,000 Swedish individuals.

For women, both waist circumference and BMI increases were linked to a 13% higher cancer risk. The study highlights the importance of considering fat distribution and sex differences when assessing cancer risk related to obesity.
