ABSTRACT
Breast cancer is the most prevalent cancer among women in the world, with a notable increasing
prevalence in recent decades. Many environmental compounds with estrogenic activity, called environmental
estrogens (EEs), which are especially persistent organic pollutants, may play important roles in the
occurrence and development of breast cancer and even treatment and prognosis. EE compounds, including
bisphenol A, nonylphenol, phthalates, perfluorooctane sulfonate, polybrominated diphenyl ethers, dioxins,
and polychlorinated biphenyls, result from industrial manufacturing and exist ubiquitously in the human
environment. With the aggravation of environmental pollution, these compounds are residual in all kinds
of environmental matrices – especially in industrialized countries. Humans are frequently exposed to them
through various pathways, including body contact, inhalation, diet, household products, dust, and cosmetics.
They have been detected in many types of human specimens. Their persistence in environmental matrices
and humans has aroused global attention because of their effect on public health, especially the occurrence of
breast cancer. In this review, we focus on recent research of these seven familiar EEs in industrial pollutants
to provide insight into the evidence for risk of breast cancer with exposure to environmental estrogen-like
chemicals and to provide clues for prevention and control of breast cancer.
