Similarities and Differences between Embryonic Implantation and CTC Invasion: Exploring the Roles of Abortifacients in Cancer Metastasis Chemoprevention

Scientists investigated the multidisciplinary data from recent large epidemiological chemoprevention studies for long-term use of oral contraceptives to reduce cancer risk and differences in cellular and molecular processes between embryonic implantation to endometrium and adhesion/invasion of circulating tumor cells to vascular endothelium.
