Abstract

Metastasis is defined as the process of spreading cancer cells from their place of origin to a distant organ. Each of the steps necessary for metastasis to occur, from the appearance of tumor cells to their growth and proliferation in the receiving organ, is driven by genetic and/or epigenetic alterations.

Due to its systemic nature and resistance to certain therapeutic agents, it is difficult to treat and is considered the cause of more than 90% of deaths due to cancer. The steps included for the development of metastasis are: (1) local invasion of the surrounding extracellular matrix (ECM), (2) intravasation into the lumen of blood vessels, (3) survival during vascular transport, (4) arrival at a distant organ, (5) extravasation into the tissue parenchyma, (6) survival in this microenvironment, and restarting their proliferative program.
