Anti-proliferative activity of green tea extract in Human Cervical Cancer Cells (HeLa)

Cancer of the cervix is the commonest genital tract malignancy in the female and it has been ranked second to breast cancer. About half a million new cases are seen worldwide each year, most occurring in developing countries (Ertem, 2009).The search for natural products which contains potential anticancer activity has begun recently. Over the past years number of approaches has been developed for clinical use and a number of anticancer drugs have been introduced. The main problems with these agents are the toxicity associated with them due to their lack of specificity, as these agents also kill healthy cells. Though a good number of anticancer agents have been developed from plants and their derived agents, development of a safe, economic and site-specific anticancer drug is still a challenge.
