“Prevention of carcinogenesis by tea polyphenols… Tea has been considered a medicine and healthful beverage for ages. The beneficial effects of tea are thought to be due to its polyphenolic components….Tea is one of the few chemopreventive agents known to have protective effects at different stages of the carcinogenic process….” http://www.ncbi.nlm.nih.gov/pubmed/11768768
“Tea and tea polyphenols in cancer prevention… The inhibitory action of tea (Camellia sinensis) and tea components against cancer formation has been demonstrated in different animal models involving different organ sites in many laboratories… tea polyphenols affect signal transduction pathways, inhibit cell proliferation and induce apoptosis,” http://www.ncbi.nlm.nih.gov/pubmed/10721932
“Cancer chemopreventive activity and bioavailability of tea and tea polyphenols… Consumption of tea has been associated with many health benefits including the prevention of cancer.” http://www.ncbi.nlm.nih.gov/pubmed/12628518
“Cancer chemoprevention by tea polyphenols… Tea is one of the most widely consumed beverages, second only to water… inhibitory effects of tea against carcinogenesis… tea polyphenols function as cancer chemopreventive agents” http://www.ncbi.nlm.nih.gov/pubmed/10786933
“Tea antioxidants in cancer chemoprevention… properties of tea polyphenols make them effective chemopreventive agents against the initiation, promotion, and progression stages of multistage carcinogenesis.” http://www.ncbi.nlm.nih.gov/pubmed/9591194
“Chemopreventive potential of flavonoids in oral squamous cell carcinoma in human studies… These flavonoids, abundant in green tea and black raspberries, respectively, represent promising chemopreventive agents in human oral cancer.” http://www.ncbi.nlm.nih.gov/pubmed/23857227
Cancer prevention by tea: Evidence from laboratory studies… The cancer preventive activities of tea (Camellia sinensis Theaceae) have been studied extensively. Inhibition of tumorigenesis by green tea extracts and tea polyphenols has been demonstrated in different animal models, including those for cancers of the skin, lung, oral cavity, esophagus, stomach, small intestine, colon, bladder, liver, pancreas, prostate, and mammary glands.” http://www.ncbi.nlm.nih.gov/pubmed/21397027
“[Anti-inflammatory effects of tea-flavonoids]… Tea flavonoids belong to the large group of polyphenols and display antioxidative, anti-inflammatory and anti-neoplastic activities… Dietary supplementation with specific tea-flavonoids… could ultimately lead to inhibition of carcinogenesis.” http://www.ncbi.nlm.nih.gov/pubmed/23233307
“Active extracts of black tea (Camellia Sinensis) induce apoptosis of PC-3 prostate cancer cells via mitochondrial dysfunction… Many studies have shown that black tea reduces the risk of several types of cancer… these findings suggest that black tea could act as an effective anti-proliferative agent…” http://www.ncbi.nlm.nih.gov/pubmed/23715786
