Angioinvasion (also known as vascular invasion) describes the movement of tumour cells into a blood vessel such as a capillary, artery, or vein. It is almost always associated with malignant (cancerous) tumours although it can also be found in some benign (non-cancerous) tumours. Angioinvasion is important because it increases the risk that tumour cells will metastasize (spread) to other parts of the body.
