Overexpression of epidermal growth factor receptor (HER), a tyrosine kinase receptor that regulates cell growth, accelerates tumor cell growth, promotes angiogenesis, and enables invasive metastasis, and is common in malignant tumors such as non-small-cell lung, breast, and pancreatic cancers, and correlates with tumorigenesis, progression, and poor prognosis. This evidence concerns the gene EGFR and neoplasm.
