Of interest?
In the 3 December 2005 issue of New Scientist magazine, I found this:
 
Pesticide link to breast growth
 
"Exposure to pesticides in the womb may change when and how breasts develop  
in young girls."
My synopsis: A preliminary study in Mexico, of 50 girls aged 8-10, both  from 
the same traditional Mayan group, similar in income, diet and  lifestyle, 
assessed breast growth among two subgroups: one from a valley  where pesticides 
were regularly applied while the other half lived in foothills  without. ( The 
article stated the girls in the foothills were children of  ranchers, and I 
suppose the assumption is that no pesticides were applied to the  animals, I 
wonder what might have been in their feed, but no one looked at  that...) 
"Girls from the valley had larger breasts than those from the foothills,  but 
LESS MAMMARY GLAND TISSUE( Environmental Health Perspectives,  
DOI:10.1289/ehp.8280). [ Caps are mine for emphasis]
    In the past, obesity has been linked to early  puberty, but measurements 
of the girls' body mass index ruled this out as the  cause of differences in 
breast development. Previous studies identified  organochlorine pesticides in 
umbilical cord blood from children born in the  valley around the same time as 
the girls in this study."
 
I wonder what the implications for breast function is, when these girls  come 
of age to birth and babyfeeding...
