Breast cancer caused by childhood diet, weight and metabolism, not just estrogen
This new evidence suggests that diet and other lifestyle factors in childhood and early life can significantly increase the risk of breast cancer - completely independent of any other factors.
Russ Hovey, a UC Davis associate professor and one of the researchers from the University of California, commented to The Examiner “Our findings suggest that diet and shifts in body metabolism that parallel changes seen during obesity and Type 2 diabetes can also stimulate breast growth entirely independent of estrogens effects. The findings of this study are particularly important when we superimpose them on data showing that girls are experiencing breast development at earlier ages, coincident with a growing epidemic of childhood obesity”.
