Targeted therapy is new type of cancer treatment that uses drugs precisely and attaches cancer cells with minimum damage to normal cells. It is multimodality cancer treatment regimens that include chemotherapy, surgery and radiation therapy. It has limited toxicity and target cancer cells which carry specific receptors (estrogen receptor).
