Until menopause, adult females have high levels of estrogen. Surplus estrogen, however, produced by visceral fat adds considerably to breast cancer risk, since estrogen at high levels stimulates breast tissue.11 Thus, increased visceral fat on a female has been associated with an increased risk for breast cancer as high as fourfold. Breast cancer risk in postmenopausal women with the visceral fat of a wheat belly is double that of slender, non-wheat-belly-bearing postmenopausal females.
