Endocrine disrupting chemicals and cancer risk (testis and breast)

There has been much concern whether Endocrine Disrupting Chemicals (EDCs) play a role in the recent increase in the incidence of certain hormone sensitive cancer forms. There is at present, however, no proven causal link between exposure to EDCs and human cancer in any of the organs supposed to be at highest risk, i.e., the testis, breast, prostate, and endometrium. This may be due to a real absence of effects, or difficulties in obtaining such data.
