Anti-Cancer Green Tea is a Cancer Fighter

November 23, 2023 5 mins to read

Green Tea has some impressive anti-cancer properties and has been a staple beverage in Eastern cultures for both it’s soothing taste and renowned health benefits. New research is catching up and studies now show potential for Green tea as a cancer fighter, specifically the catechins it contains. So, In this article I’m going to look into Green Tea and it’s potent cancer fighting potential.

The Science Behind the Leaves

Green tea owes its health-promoting prowess to catechins, naturally occurring phytochemicals found in the Camellia sinensis plant. Among these, epigallocatechin gallate (EGCG) is the primary compound being studied for its potent anti-inflammatory and anti-cancer activities​​​​.

Research has consistently highlighted green tea’s role in cancer prevention and treatment. It acts as an angiogenesis inhibitor, meaning it can help block the formation of new blood vessels that tumors need to grow​​, essentially cutting off their supply lines. Additionally, green tea and its catechins have been shown to have both chemo-preventive (anti-tumor) and chemotherapeutic (used along-side chemo) effects in various types of cancer​​. Essentially this means Green Tea and EGCG can be a preventative measure against cancer, and is often used in coordination with traditional treatments like chemo.

EGCG Antioxidant & Anti-Cancer

EGCG isn’t just a regular antioxidant, studies have shown its efficacy in preventing oxidative damage to healthy cells and modifying cellular responses to chemotherapy, making it a promising anti-tumor agent​​. Its safety, low cost, and easy availability make EGCG a powerful ally in the fight against cancer.

Quality & Purity

When choosing green tea for its medicinal benefits, the type and origin of the leaves is important. Unfermented green tea has the highest concentration of catechins as well as those green teas sourced from Korea and Japan, with different teas having varying concentrations of these vital molecules​​. You can also get over the counter (OTC) EGCG supplements, a highly concentrated extract of the compound. However I often preference the whole plant vs extracts, due to potential beneficial interactions that occur between it’s various compounds, and which science doesn’t yet fully understand.

Matcha Green Tea: A Medicinal Powerhouse

Matcha, my favorite form of green tea, deserves special mention here. It’s not just a tea steeped in tradition; it’s also concentrated source of EGCG vs other green teas. Its unique composition and high antioxidant content make it a top choice to obtain it’s medicinal properties. In my professional opinion, If you are looking to matcha green tea for it’s medicinal (and anti-cancer) properties, you should settle for nothing less than, organic therapeutic grade matcha green tea powder; preferably tested for purity and using distilled or reverse osmosis filtered water (to clean out toxic chemicals).

Cancer Types and Prevention

Green tea’s benefits extend to various types of cancers, including: lung, breast, esophageal, stomach, liver, and prostate cancer. The amount and concentration of green tea consumption also play a role in its efficacy​​. Studies suggest that a regular and substantial intake of green tea can significantly reduce the risk of certain cancers​​. Personally, I suggest a combination of matcha green tea + EGCG supplements, because well, it’s just easier than trying to drink a ton of matcha each day.

A Word of Caution

While green tea is a powerful ally against cancer and for optimal health, it’s not a cure-all. Researchers caution against overestimating its effects, especially since most studies have been conducted in East Asia, where dietary and lifestyle factors differ significantly from Western countries​​. In other words, there could be other dietary, and lifestyle factors at play here. Also, green tea should complement, not replace, standard cancer treatments.

Embracing a Healthier Lifestyle

Green (Matcha) tea and it’s catechins, particularly EGCG are well studied around the used for their cancer fighting potential. Incorporating green tea into our daily routine can be an excellent part of an anti-cancer diet & lifestyle as well as to promote optimal health. Green Teas potential in reducing risks of various diseases, including cancer, makes it a worthwhile addition to a healthy lifestyle.
