DDT intake in US peaked in 1965, but in Mexico was not banned until 2000 for example, therefore is relevant to have a recent review here. We have learned a lot and clearly linked the substance with lots of unwanted and undesired effects since 1972.<p>Women develop breast cancer typically around 50 years age ( the median age at diagnostics is 61) with around 230.000 new cases in US in 2015, and at a relatively stable rate (~12% of women). Thus we are far away to see the real results of DDT banning in US. Maybe we will not have a clear answer until 2022, when the women born in 1972 will reach 50 years.
