[Is the vascular-endothelial growth factor responsible for the malignancy of lung cancer?].

Lung cancer is the most common malignancy in the world. Its large ability to regional extension of the tumor and formation of local and distant metastases causes that the number of deaths and cases of disease are almost identical. The reason of this ability lies in the creation process of blood vessels that is angiogenesis, which main stimulus is the vascular-endothelial growth factor (VEGF).
