@XysflightchampX, It?s impossible to test on humans. First, you can?t isolate unexposed controls, because everyone is exposed to BPA ? it?s ubiquitous. Second, exposing? humans to large amounts of a suspected carcinogen would be unethical and illegal. Third, cancer takes so long to develop you would longitudinal studies that are being done but without proper controls. BPA acts as an estrogen that our bodies can?t recognize or neutralize, and excess estrogen causes breast cancer.
