Abstract
The global burden of cancer continues to increase mostly because of the aging,
factors like exposure to UV radiation, pollution and a rise in the adoption of cancer
causing behaviors (obesity, poor diet, smoking habits etc.). Breast cancer is the most
frequently diagnosed cancer and the second leading cause of cancer death among
females. Latest statistics estimated almost with greater than 1,300,000 cases and 450,000
deaths each year world-wide. Clinically, this heterogeneous disease is categorized into
three basic therapeutic groups (Jemal, 2011).
