Prenatal exposure to bisphenol A (BPA) altered the growth  of mammary tissues in ways that increase the risk of breast cancer  and increase the sensitivity of breast tissue to cancer causing  agents.
 Cell studies of BPA show major  changes in cell signaling down to 0.23 parts per trillion. This is the lowest  dose that has ever been tested, and it caused biologically important effects.  With six billion pounds of BPA produced each year, no wonder  there is such resistance  to these low level results.
 If EPA were to use 2.5 ppb from the current experiment  as a LOAEL and apply the same logic used to establish the current standard, the  reference (safe) dose would be 2.5 parts per trillion.  Linked from here
