Current State of Technology for Therapeutic Treatment of Breast Cancer

Abstract

Breast cancer develops when cells in the breast tissue begin to grow in an uncontrolled manner. These cells usually form a tumor that can often be seen in an x-ray or felt as a lump. Tumors are often unresponsive to normal physiological stimuli. At the center of a tumor are typically dead or dying cells that produce biomarkers that can be analyzed for the presence of the tumor. In the last ten years, various new drugs have been introduced in the international markets to treat breast cancer tumors. These drugs are administered either orally or via an injection. In this review, an insight is provided into the different signal transduction pathways that are being targeted for the for adjuvant breast cancer treatment by the use of hormoneblocking agents, chemotherapy and monoclonal antibodies.
