Laboratory Studies Show Immense Success
Most of the studies that have been done on green tea and cancer have been done in a laboratory rather than on human subjects. All testing must go through rigorous laboratory trials before it can be done on humans to make sure that it is safe.
Laboratory studies on green tea have shown immense benefits of green tea as a cancer-fighting agent, particularly the high levels of EGCG that it contains. Everything from killing cancer cells to shrinking tumors points to its enormous capacities. There seems to be no contest regarding its potency and its use in anti-cancer treatments and therapies. But as always, there is a catch.
