<unk>  is the invasion of cancer cells through the basement membrane into a blood or lymphatic vessel.<unk>  is one of several carcinogenic events that initiate the escape of cancerous cells from their primary sites. Other mechanisms include invasion through basement membranes, extravasation, and colonization of distant metastatic sites. Cancer cell chemotaxis also relies on this migratory behavior to arrive at a secondary destination designated for cancer cell colonization.
