Green Tea Cancer Studies
In the last two decades, over 1800 studies have demonstrated that consuming green tea can reduce the risk of various cancers.
Studies have reported significantly reduced risk of breast cancer, prostate, skin, colon, brain, cervical, ovarian, liver, esophageal, stomach, and others, including overall lifetime cancer risk reduction.
These studies include preliminary cell studies, animal studies, human demographic comparisons, cohort studies, case-controlled research, and some green tea cancer trials.
How is green tea effective against cancer cells?
It contains many rare chemicals that are beneficial for humans.
Each chemical can work in different, and sometimes multiple biochemical pathways that influence the development of cancers.
The chemicals include green tea catechins, such as (EGCG) which are powerful antioxidants that can protect against carcinogenic damage.
In addition, green tea helps anti-inflammatory pathways and DNA protection.
Researchers have discovered that green tea can reduce the risk of cancers during initiation of cancerous cellular changes, progression of tumors, and proliferation of malignant cells throughout the body.
It is important to understand that green tea cancer research is reported as risk reduction for one group using green tea compared to a similar group not using green tea.
This research cannot predict individual variations, and if you have a health condition or concern, you must consult with your health care provider for individualized results.
While most of this research is considered preliminary, some large statistical reviews (meta analysis) have confirmed significantly less cancer with daily consumption of approximately five cups of green tea daily.
