Biologic agent epigallocatechin gallate (EGCG).
EGCG alters the metabolism of cancer cells, slows the spread of the disease.
EGCG reduces overall cancer risk.
Decreases cancer progression by suppressing lactate dehydrogenase expression in cancers.
Green tea and green tea extracts are widely consumed, especially by patients with cancer.
No clinical evidence that it slows cancerprogression and may interfere with anti cancer agents.
Should be avoided in regimens that include bortezomib or radiotherapy.
May be associated with increasing radiotherapy skins burns when applied topically.
