can control," Dorgan said. "The effect of obesity on breast cancer risk is important because the prevalence of obesity is high and increasing." According to Dorgan, the estimated prevalence of obesity in U.S. women aged 60 to 74 increased from 29 p...
Genetic clues may show which women face breast cancer risk from HRT

enters menopause, hormone levels plummet and breast cell multiplication slows. Hormone replacement therapy in postmenopausal women introduces hormones present in very small amounts in such women. That means additional breast cell multiplication--and ...
