The process of angiogenesis is regulated by several growth factors, the most important factor is VEGF which is an important mediator because it facilitates the growth of blood vessels and the remodeling processes. In addition, angiogenesis is significantly involved in tumor progression giving the tumor the necessary supplies for its survival and thus causing metastases in other organs by providing a site of entry to the circulation of vessels blood. The objective of this review is to reflect the fundamental role that angiogenesis has in the development and spread of cancer through vascular endothelial growth factor, its receptors, and its signaling pathways. On the other hand, antiangiogenics strategies (angiogenesis inhibitors) are proposed to fight cancer and clinical trials are presented to verify the survival range of patients who have been treated with anti-angiogenic therapy.
