Human Exposure: 52-74ng/kg/day

How does the endocrine system work?

BPA increased the level of hormone receptors produced by a prostate gland cell

Some dosages of BPA were environmentally relevant

An increase in cell receptors fuels growth of the cell Cells can proliferate out of control, resulting in

cancerous tumor cells.

Conclusions BPA is harmful in lower doses BPA can leech into food/beverages at

relevant levels BPA exposure increases risk of cancer
