COPENHAGEN, Denmark, Sep 25, 2009 (UPI via COMTEX) -- Higher levels of
environmental chemicals in breast milk are linked to a higher incidence of
testicular cancer, researchers in Denmark found.
Konrad Krysiak-Baltyn and colleagues in Denmark, Finland and Germany measured
levels of 121 chemicals in 68 breast milk samples from Denmark and Finland to
compare exposure of mothers to environmental endocrine disrupting chemicals.
There is a worldwide increase in testicular cancer, but the cause remains
unknown, Krysiak-Baltyn said.
In some countries, such as Denmark the prevalence of this disease and other male
reproductive disorders is conspicuously high, while in Finland the incidence are
markedly lower, Krysiak-Baltyn said.
"We were very surprised to find that some endocrine disrupting chemicals levels,
including some dioxins, PCBs and some pesticides, were significantly higher in
Denmark than in Finland," Niels Skakkebaek, a senior member of the research team
at the Rigshospitalet in Copenhagen said.
"Our findings reinforce the view that environmental exposure to endocrine
disrupting chemicals may explain some of the temporal and between-country
differences in incidence of male reproductive disorders."
The findings are published in the International Journal of Andrology.
