Breast cancer affects the breast tissue. There are two forms of this cancer: one type originates from the ducts and is commonly known as ductal carcinoma while that which originates in the lobules is termed as lobular carcinoma. In women, breast cancer accounts for over 22 percent of all cancers (Suter & Marcum, 2007). The molecular underpinnings of breast cancer are very complex and have different cellular pathways particularly those of cell growth and proliferation. Examples of these pathways include MAPK; TP53; P13K/AKAT/mTOR and RB/E2F (Suter & Marcum, 2007). At the molecular level, these pathways are a representation of molecular mechanisms ...
