title: A comparison of mammographic parenchymal patterns in premenopausal Japanese and British women.
abstract: Normal premenopausal Japanese women have significantly more favourable mammographic parenchymal patterns (Wolfe Grades) than comparable British women. This finding is unaffected when the women are stratified by age, Quetelet's Index, age at menarche, age at first birth, and parity.
