Epidemiologic studies hae also suggested that green tea consumption might be effective in the prevention of certain human cancers. The distribution of cells in different phases of the cell cycle was analyzed by flow cytometry. Confocal microscopy and flow cytometry confirmed the findings. Green tea may protect against cancer by causing cell cycle arrest and inducing apoptosis. It needs to be evaluated in human trials.
Prostate cancer is the most commonly diagnosed cancer in American men.
In 1996, an estimated 317,100 new cases of prostate cancer, and 41,400 deaths from prostate cancer will be found, among men in the United States. It is the second most common cause of death in men older than 55. We are detecting prostate cancer within the past decade with increasing frequency, and many patients with this condition are receiving such treatments as radical prostatectomy and radiation therapy for cure. Although refinements in PSA-based testing have contributed substantially to the increased detection rate of prostate cancer, the incidence of disease was increasing dramatically even before the detection of PSA was possible. Self medication for prostate disorders has increased throughout the U.S. and the rest of the world.
