Every day, tiny cancer cells can emerge inside the human body. Yet most people never develop cancer and continue living healthy lives for decades.
According to Dr. William Li, speaking on the DOAC podcast:
"The real question isn't why cancer happens—it's why it doesn't happen more often."
This remarkable mystery is reshaping how scientists think about health, immunity, nutrition, sleep, and longevity. The human body is constantly detecting, controlling, and eliminating abnormal cells before they become a threat.
The fascinating challenge for modern medicine isn't simply understanding cancer itself—it's uncovering the powerful biological defenses that keep millions of people healthy despite the presence of potentially dangerous cells.
The more we learn about these natural protective mechanisms, the closer we may come to unlocking new strategies for disease prevention, healthier aging, and longer lives.
The human body has about 40 trillion cells, more than the stars in the clear sky. Each cell copies itselfby doing
But this copying process makes 10,000 mistakes every day, each mistake a microscopic cancer. Yet we don't die because the body has a hardwired defense system.
The immune system detects and destroys these cancer cells, just as the police patrols and picks up the drug dealer standing on the corner.
There are already 1 billion of the 1 cm breast tumors that can be felt by hand there are cancer cells. It takes 10 million blood vessels to feed these one billion cells.
And when a single blood vessel enters a tumor, it grows 16,000 times larger in just two weeks. This is Angiogenesis, Dr. Li's research center.
Let's get straight to the bad food. Excess sugar weakens the immune system. Daily alcohol increases the risk of breast cancer by increasing estrogen. Processed meat World Health Organization Direct carcinogen in judgement.
But Dr. Li said it's okay to have a burger or a hot dog once in a while. The problem is the daily habits.
There is no such thing as a superfood. It's marketing. But certain foods work against certain diseases. There are also cautions with electrolyte drinks. Most people don't need extra sodium, but excess sodium damages blood vessels and accelerates aging.
Added sugar is the body's immune system Interferes with cells. A type of immune cell called neutrophils detects and kills cancer. Eating too much sugar causes these neutrophils to lose function. Simply put, sugar puts your body's police to sleep.
Alcohol travels to the liver to produce a chemical called acetal dehyde, which damages DNA. It also increases estrogen, which is directly linked to breast cancer. But Dr. Li said drink a little now and then not totally forbidden, but dangerous if it's routine.
The stress hormone cortisol weakens immune cells. But the most terrifying connection is between sleep and stress. Less sleep leads to stress, more stress leads to less sleep. In this cycle, the body loses its ability to destroy cancer cells.
The Glymphatic System is the brain's drainage network that only functions during deep sleep. This is to remove amyloid plaque from the brainwhich causes Alzheimer's. And deep sleep releases growth hormones that break down visceral fat. Means enough sleep clears the brain and also reduces belly fat.
Why is cancer increasing among young people? Colorectal cancer is increasing among people in their 30s and 40s. Dr. as a reason. Lee said daily consumption of processed meat directly increases the risk of large intestine cancer. Besides microplastics.
Research It says people ingest about a credit card's worth of microplastics every week. They have been found in human blood, lungs, placenta, and more recently in heart tissue. Microplastics cause inflammation in the body and interfere with the hormonal system.
Avoid keeping hot food in plastic containers. Stay away from t-bags because plastic t-bags contain billions of microplastics in hot waterleaves
The most surprising discovery in Dr. Li's research is that the idea that Japanese green tea is the best of all green teas is wrong. Tests in his lab showed Earl Gray tea to be the most potent at protecting blood vessels. This special power is due to bergamot citrus.
And matcha is the most polyphenol-rich tea because the whole tea leaves are ground and drunk, not just steeped in water. Polyphenols found in matcha link breast cancer destroyed stem cells.
Cancer returns mainly because of these stem cells. Purple potato anthocyanins destroy colon cancer stem cells.
The most human moment of the podcast was when Dr. Li shared his experience. People close to him have been diagnosed with cancer and that experience led him to research the link between food and cancer.
He said this is the last time he sees cancer as a doctorbecoming visible. He has seen patients go from stage four cancer to stage zero.
AI is now analyzing data from thousands of cancer patients together to find patterns that are impossible for humans to see. AI can predict which foods have the most impact on which types of tumors, which patients will respond well to which treatment. This is paving the way for personalized cancer treatment.
Who responds to immunotherapy?Who will and who won't depends on the bacteria in the patient's gut. Cancer treatments work when certain bacteria such as blautia and lactobacillus are present.
Medicines do not work if these bacteria are not present. Ways to boost this bacteria are fibrous vegetables, fermented foods and a varied plant-based diet.
Which is the best diet? Dr. Li doesn't advocate any one diet. Mediterranean both the diet and the Japanese diet are effective because both emphasize seasonal and local foods, less processed foods, and more variety.
Why is Japan one of the healthiest countries in the world? The Japanese eat a lot of seafood and fermented foods such as miso. More fish means more omega-3s that reduce inflammation. Miso means beneficial bacteria for the gut microbiome.
Besides, the Japanese principle of "Harahachibu" is to eat 80% full turn off This normal calorie control protects long-term health.
Subcutaneous fat is fat under the skin, which is basically harmless. Visceral fat is the fat around the organs, which is dangerous. This visceral fat puts pressure on the organ like a tube of cream inside a suitcase and causes inflammation.
A 13-year study of 3,000 Swedish normal-sized women found that those with more visceral fat the risk of breast cancer is three times higher. Excess visceral fat increases the risk of a total of 15 types of cancer, including colon, ovarian, lung, prostate.
Coffee contains a polyphenol called chlorogenic acid. Studies have shown that drinking coffee helps reduce visceral fat. Dr.Li was also surprised in this news. However, adding milk or sugar reduces this benefit.
Does fasting reduce visceral fat? yes 16 to 18 hours of fasting to the body burns visceral fat. Because the body preferentially uses visceral fat in a state of ketosis. But fasting should not be done without qualified guidance.
Diet is directly linked to Alzheimer's, Parkinson's and dementia. Foods that increase inflammation also damage the brain. Fish, turmeric, and berries especially rich in omega-3s are neuroprotective.
Dr. Li's main message is that medicine does not cure disease;Controls symptoms. But the right food strengthens the body's own defense system. Research by the Angiogenesis Foundation has found more than 200 foods that can stop the blood supply to cancer.
Should I take supplements? Dr. Li said supplements are not a substitute for food. Most people do not need supplements if they eat a varied plant-based diet. The exception is vitamin D if you get less sun.And don't eat omega-3 fish.
The most anticipated answer to the podcast Dr. Lee said his top five picks, based on science, are:
Matcha Green Tea
Matcha contains exceptionally high levels of polyphenols and antioxidants because the entire tea leaf is consumed rather than simply steeped.
Coffee
Research suggests coffee may support liver health, metabolic function, and cognitive health when consumed in moderation.
Tomatoes
Tomatoes are rich in lycopene, a powerful antioxidant extensively studied for its potential protective benefits.
Purple Fruits and Vegetables
Blueberries, blackberries, purple sweet potatoes, red cabbage, and similar foods contain anthocyanins—compounds associated with anti-inflammatory and antioxidant effects.
Fermented Foods
Foods such as yogurt, kefir, kimchi, and miso help nourish beneficial gut bacteria that play important roles in immunity and overall health.
💚The Most Important Lesson
Your body is not helpless.
Every day, it fights infection, repairs damage, regulates inflammation, and removes abnormal cells.
The choices you make consistently—what you eat, how you sleep, how you manage stress, and how active you remain—help determine how effectively these natural defense systems perform.
There is no single superfood.
No magic supplement.
No instant cure.
But science continues to show that healthy habits can strengthen the body's remarkable ability to protect itself.
And that may be one of the most empowering health discoveries of all.
