Prostate cancer is the second most common cancer in
men, responsible for an estimated 220,000 cancer diagnoses in 2015 alone.
Recent cancer research has focused on the possible role botanicals might play
in the prevention and treatment of cancer. Researchers at Moffitt Cancer Center
conducted a randomized trial to determine the safety and efficacy of green tea
catechins in preventing the progression of prostate cancer in men with
premalignant lesions.
Green Tea’s Impressive Reputation
Green tea as a possible cancer
preventative isn’t new news. We know that 20% of green tea is consumed in Asian
countries that boast remarkably low death rates from prostate cancer. We also know
that prostate cancer risk increases greatly among Asian men who settle in the
United States and forego their green tea drinking habits.
Lab studies show that active compounds
called catechins in green tea help to suppress cancer cell growth, motility,
and invasion, and trigger cancer cell death. Animal models confirm the
cancer-protective benefits of green tea catechins, which help to prevent tumors
and stall tumor growth.
Epigallocatechin-3-gallate (EGCG)s
the primary catechin in green tea, and is credited with its cancer-fighting
powers.
