  • HER-2 a Predictive Marker For Breast Cancer Treatment    By: goldy yadav

    Cancer is a deadly disease in which disorder occurs in the normal process of cell division, which is controlled by the genetic material (DNA) of the cell (1). There are over 100 different types of cancer, and each is classified by the type of cell that is initially affected. Cancer harms the body when damaged cells divide uncontrollably to form lumps or masses of tissue called tumors. >> Category: Biotech Research
