A significant correlation is thought to exist between the number and density of blood vessels and the metastatic states, tumor size, histological type, and consequently degree of tumor malignancy because blood vessels are an important part of the tumor stroma and angiogenesis is a predictor of prognosis in many human neoplasms. Angiogenesis is a critical step in the progression of tumor growth and metastasis potential.
