For those who don't drink green tea, it might be wise to reconsider. According to research, drinking green tea may help prevent the spread of prostate cancer.This is because the polyphenols found in the tea target molecular pathways that shut down the production and spread of tumor cells.
Further, they inhibit the growth of tumor-nurturing blood vessels.
The study, which involved using a mouse model for human prostate cancer, indicated the consumption of green tea polyphenols (GTP) adjusted and reduced levels of the insulin-like growth factor-1 (IGF-1)-driven molecular pathways in prostate tumor cells.
The findings supported other studies, which found that increased levels of IGF-1 were associated with the increased risk of various cancers, including:
- Prostate
- Breast
- Lung
- Colon
Researchers also discovered that these GTP reduced the expression of proteins typically linked to the metastatic (additional location) spread of cancer cells. This is because the polyphenols inhibited the levels of urokinase plasminogen activator as well as cellular molecules linked to the metastasis.
