Image:Tumor-driven Angiogenesis

Description: A illustration of the progression of angiogenesis, which is the physiological process involving the growth of new blood vessels from pre-existing vessels. Tumours cannot grow beyond a few mm due to a lack of oxygen and other nutrients, so they encourage the formation of blood vessels to support their rapid cell division. For this reason, angiogenesis is a fundamental step in the transition of tumors from a dormant state to a malignant one.
