Are Lipstick Chemicals Changing Your Cup Size?
February 09, 2008
In less than a decade, the average bra size in Britain has increased from a 34B to a 36C. A quarter of all bras sold are a D cup or above, which is double the number sold three years ago, and the range of standard bra sizes now end at K instead of G.
There are a number of reasons for the increase, including obesity and environmental factors. One possible cause is the increased presence of xeno-estrogens, chemicals which mimic the effect of estrogen and are fat-soluble, which means they store themselves in your body. Xeno-estrogens are found in many places, including cosmetics such as lipstick.
The female breast contains cells called estrogen receptors which are stimulated by the presence of estrogen (or xeno-estrogens) into producing more mammary tissue. It is possible that stimulating these cells artificially after menopause, when natural estrogen levels drop, could contribute to breast cancer.
