Green tea and cancer have been widely studied, with research exploring its potential role in cancer prevention and cancer therapy. During my stage IV colorectal cancer treatment, I incorporated green tea consumption into my routine alongside chemotherapy, surgery, and lifestyle changes.
Diagnosed with metastatic rectal cancer, I faced multiple tumor recurrences despite following standard medical treatments. I focused on green tea polyphenols, particularly epigallocatechin 3 gallate (EGCG), to support my body while adjusting my diet and fasting regimen. Drinking green tea daily became part of my approach to managing cancer risk, maintaining energy, and improving overall health.
My Diagnosis and Initial Challenges
A stage IV rectal cancer diagnosis with liver metastases changed everything. A CEA tumor marker over 2000 and multiple liver tumors confirmed the severity of my condition. Doctors recommended aggressive chemotherapy, radiation therapy, and multiple surgeries, but the side effects were overwhelming—fatigue, nausea, weakness, and weight loss.
Searching for ways to support my body during cancer treatment, I explored dietary changes, fasting, and natural compounds that could work alongside standard medical care. Green tea consumption stood out as a potentially beneficial addition, leading me to research its effects on cancer cells, inflammation, and overall health.

Understanding the Benefits of Green Tea
Green tea has been widely studied for its health benefits, particularly in cancer prevention and cancer therapy. It contains powerful antioxidants that may help reduce inflammation, support immune function, and influence cancer cell behavior. Many clinical studies, laboratory studies, and in vitro studies have explored its effects on lung cancer risk, prostate cancer risk, and colorectal cancer risk.
Key Components of Green Tea:
- Green Tea Catechins – Bioactive compounds that may help inhibit cancer cell proliferation and induce cell cycle arrest.
- Epigallocatechin 3 Gallate (EGCG) – A potent polyphenol linked to effects on breast cancer cells, lung cancer cells, and colon cancer cell lines.
- Tea Polyphenols – Antioxidants that may help in inhibiting tumor angiogenesis and decreasing tumor growth.
- Green Tea Extracts – Used in research to examine the effect of green tea on human lung cancer cells, breast cancer cell lines, and prostate cancer cells.
- Catechins and Cardiovascular Disease – May support heart health and reduce risks of coronary artery disease and high blood pressure.

Discovering Green Tea as a Supportive Treatment
Searching for ways to support my body through chemotherapy and surgeries, I began reading cancer research, review and meta-analysis papers, and expert interviews. Many studies suggested a connection between green tea intake and decreased risk of several cancers, including colon cancer, bladder cancer, stomach cancer, and gastric cancer. Scientists have explored green tea polyphenols for their role in inducing cell cycle arrest, inhibiting tumor angiogenesis, and affecting lung cancer cell lines.
Cancer prevention and treatment experts discussed how green tea composition could influence cancer cells and cell apoptosis. Some findings suggested that green tea catechins might interact with key cancer-related pathways, such as vascular endothelial growth factor and epidermal growth factor receptor. While I knew green tea was not a cure, I decided to drink green tea daily to see if it could help support my overall health.
Deciding to Use Green Tea
Adding green tea to my routine was a decision based on scientific research and personal experience. Studies on green tea polyphenols, epigallocatechin 3 gallate (EGCG), and tea catechins suggested that these compounds might help reduce inflammation, induce cell cycle arrest, and support overall health. Cancer treatment left me weak, and I was looking for ways to support my body without interfering with chemotherapy or surgery recovery.
Before making any changes, I discussed green tea consumption with my oncologist. While doctors didn't claim it could treat cancer, they assured me that drinking green tea was safe. No clinical studies suggested it would negatively affect chemotherapy, so I decided to make it part of my daily cancer therapy routine.
Incorporating Green Tea into My Daily Routine
Green tea intake became a structured part of my day. I prepared 1000 cc of green tea in the morning and drank it throughout the day. Green tea extract wasn't my choice—I preferred whole green tea for its full spectrum of polyphenols. My routine combined fasting, supplements, and exercise, focusing on supporting my immune system, reducing cancer risk, and maintaining overall health.
What Does My Green Tea Routine Look Like?

11:00 PM (Evening) | Evening supplements |
Benefits of Green Tea During Cancer Treatment
Drinking green tea became a key part of my daily routine while undergoing chemotherapy, radiation therapy, and surgeries. Research on green tea polyphenols, catechins, and antioxidants suggested potential benefits in reducing inflammation, supporting the immune system, and affecting cancer cell behavior. Including green tea in my cancer therapy plan helped me manage side effects and maintain overall well-being.
Antioxidant Properties and Their Role in Reducing Cancer Cell Growth
Green tea catechins, especially epigallocatechin 3 gallate (EGCG), have been studied for their effects on cancer cells. Some research suggests that they may help induce cell cycle arrest and inhibit tumor growth in breast cancer cells, prostate cancer cells, lung cancer cells, and colon cancer cell lines. The antioxidant properties of green tea extracts may also protect healthy cells from damage caused by chemotherapy and oxidative stress.
Enhanced Immune Function and Reduced Inflammation
Inflammation is a major concern during cancer treatment, especially for patients undergoing chemotherapy, radiation, and surgery. I monitored my C-reactive protein (CRP) levels to track inflammation, and I noticed that green tea intake, along with my low-carb diet and fasting, helped keep inflammation under control. Tea polyphenols may play a role in inhibiting tumor angiogenesis, which could help slow cancer cell proliferation.
Improved Digestion and Overall Sense of Well-Being
Green tea became an essential part of my digestive health routine. During treatment, I dealt with gut issues, bloating, and changes in appetite. Drinking green tea after meals helped with digestion and reduced discomfort.
Combining it with kefir, sauerkraut, and olive oil supported my gut microbiome, which is essential for overall health. Green tea composition also seemed to help with energy levels, reducing the mental fog caused by chemotherapy.
Overcoming Challenges with Green Tea
Finding high-quality green tea and ensuring consistent green tea consumption was not always easy. Many brands sell green tea extract high in additives or low-quality green tea with little nutritional value. I also had to balance tea consumption with other dietary needs, ensuring it did not interfere with fasting periods, supplement absorption, or meal timing. Managing cancer risk involved more than just one strategy—I had to integrate nutrition, fasting, exercise, and medical treatment into a single plan.
How Did I Address These Issues?
Researching and selecting reputable sources of green tea became essential. I avoided flavored or processed versions and chose high-quality, organic loose-leaf green tea for its full range of tea catechins and antioxidants. To balance green tea intake with my diet, I included it in my morning, afternoon, and evening routine, often pairing it with meals, supplements, and fasting periods. This approach helped me make drinking green tea a consistent habit while keeping my overall cancer therapy plan in focus.
Monitoring My Health
Tracking my health became a priority while incorporating green tea consumption into my routine. I used the Oura Ring to monitor sleep quality, heart rate variability (HRV), and recovery levels, ensuring that my body responded well to my lifestyle changes. Checking these metrics daily helped me adjust my exercise, fasting periods, and green tea intake to maintain stability during cancer treatment.
Regular check-ups, blood tests, and imaging scans were essential for evaluating my progress. During oncology consultations, I monitored key markers like CEA levels, inflammation (CRP), and overall immune function to assess any potential effects of green tea polyphenols and other dietary changes. These medical evaluations helped ensure that drinking green tea was a safe and beneficial addition to my cancer therapy plan.

Lessons from My Green Tea Experience
Drinking green tea daily became an important part of my cancer treatment journey. Beyond just a beverage, it played a role in supporting my body through chemotherapy, radiation, and multiple surgeries.
The Significant Impact of Green Tea on Overall Health and Cancer Treatment Outcomes
Adding green tea catechins and epigallocatechin 3 gallate (EGCG) to my daily routine helped with inflammation, digestion, and mental clarity. Research has explored its effects on cancer cell lines, tumor growth, and cancer prevention, and I noticed improvements in my energy, digestion, and immune function.
The Importance of Consistency and Discipline in Incorporating Green Tea into My Routine
Results did not happen overnight. Consistently drinking green tea alongside my low-carb diet, fasting, and exercise was key. Regular intake ensured I was maximizing its antioxidant properties, making it a supportive tool in cancer therapy rather than just an occasional drink.
The Value of Combining Green Tea with Other Healthy Lifestyle Practices
Green tea alone was not a cure, but when combined with fasting, anti-inflammatory foods, exercise, and medical treatment, it contributed to my overall health benefits. Staying active, maintaining a strong immune system, and tracking my inflammation markers all played a role in reducing cancer risk and improving my recovery.
