Carlos Sonnenschein

CARLOS SONNENSCHEIN is a Professor at Tufts University School of Medicine, and an International Fellow at the Centre Cavaillès, Ecole Normale Supérieure, Paris, France. He was a Fellow at the Institute of Advanced Studies-at-Nantes, France. For over five decades, Dr. Sonnenschein’s research has centered on a) the control of cell proliferation by estrogens and androgens, b) the impact of endocrine disruptors on organogenesis and the reproductive function and c) carcinogenesis during early development and adult life and, specifically, on the role of stroma/epithelial interactions on rat and breast carcinogenesis. In 1999, Drs Sonnenschein and Dr. Ana M Soto co-authored a book entitled THE SOCIETY OF CELLS (Bios-Springer-Verlag) in which they critically evaluated the fields of control of cell proliferation and carcinogenesis. They concluded that a) the default state of all cells is proliferation, and that b) sporadic cancers (over 95% of clinical cases) are anchored at the tissue level of biological organization. These are the core premises of their theory of carcinogenesis and metastases, i.e., the tissue organization field theory (TOFT).
