Green tea has anti-tumor effects in breast cancer cells, according to a new study published in the December issues of the Journal of Cancer Biology and Therapy.

A team of scientists led by Dr. Radha Maheshwari, professor of Pathology at the Uniformed Services University of the Health Sciences (USU), and Rajesh Loganathan Thangapazham, a graduate student, also identified the mechanisms involved in the inhibiting effects of green tea.

The study observed that green tea can inhibit the invading capacity of breast cancer cells and have also identified the mechanisms involved in death inducing and invasion inhibiting effects of green tea.

Epidemiological studies, the scientists suggest, show that the risk of breast cancer is found to be less in Asian countries consuming green tea.

A study by Dr. Maheshwari published early this year in Cancer Letters showed that green tea is effective in delaying tumor incidence as well as in reducing the tumor burden, Newswise reported. Green tea was found to inhibit growth of tumors as well as induce death of breast cancer cells.

These studies have greater clinical significance since the ability of these phytochemicals to activate anti-cancer program of tumor cells might determine the success of chemotherapy.
