EGFR and cancer: The receptor for EGF is called epidermal growth factor receptor (EGFR) and has been found overexpressed in many types of cancer (Modjtahedi and Dean 1994), where it mainly promotes proliferation and survival of malignant cells and, by inducing expression of angiogenic growth factors and metalloproteinases, promotes tumour vascularization and metastasis (De Luca et al. 2008).
