Oral Cancer: The research team led by Joshua Lambert concludes that EGCG can set off mitochondrial damage in tumors and activate programmed cell death. The team experimented by growing Oral Cancer cells and normal cells in Petri dishes and exposed the contents to EGCG. EGCG selectively chose the SIRT3 in Oral Cancer cells and affected its mitochondrial function, whereas it didn’t hurt the SIRT3 in healthy cells. In fact, the opposite happened. The researchers noted that EGCG increased the mitochondrial membrane potential in healthy cells, which is required for efficient metabolism.

Leukemia: A scientific study published in the British Journal of Cancer explored whether there are any visible links between the intake of Green Tea and the risk factor of Leukemia by studying 107 adults diagnosed with chronic lymphocytic Leukemia. The results of the case study indicate that Green Tea can reduce the risk of developing leukemia, especially if consumed frequently in higher amounts. EGCG causes caspase-dependent death in chronic lymphocytic Leukemia cells.

Lung Cancer: A 2010 Taiwanese study observed tea drinking and smoking habits of around 500 people, and the researchers learned that those who did not drink Green Tea had a five times higher risk of developing Lung Cancer. Among smokers, the study found that the risk was twelve times higher. Recent research proved that EGCG could raise the levels of mi-R210 in Lung Cancer cells. Cells with higher levels of mi-R210 multiplied with less agility than Lung Cancer cells with lower levels of mi-R210. Additionally, Lung Cancer cells with higher levels of mi-R210 lost the ability to grow atop each other, thus curbing the severity of cancer.

Ovarian Cancer: A case-controlled study conducted in China during 1999 and 2000 discovered significant dose-response relationships between Green Tea and ovarian cancer, i.e., the increased duration and frequency of Green Tea consumption could reduce the risk of developing Ovarian Cancer.

Prostate Cancer: Susanne M. Henning suggests that men who consumed Green Tea frequently had less prostate tissue inflammation associated with cancer growth when compared to those who didn’t drink it. Her team studied 79 men with Prostate Cancer and found that the polyphenols in Green Tea could target prostate tissue and modify the inflammation of the prostate.

Breast cancer: A 2017 research checked the breast density in women who were administered with an EGCG supplement for an entire year. Those with a higher breast density have an increased risk of getting diagnosed with Breast Cancer. Although the EGCG supplement didn’t affect the breast density in older women, it caused a significant decrease in breast density in younger women.

Colorectal cancer: The results of the study published in Carcinogenesis points out that Green Tea can stop Colorectal Cancer in its tracks by particularly targeting colon carcinogenesis in its initial stages. However, the EGCG in Green Tea might not be able to affect or inhibit the growth of adenocarcinomas formed before the administration of Green Tea.
