For a top medical professional, discovering a new tumor in the same lung lobe just five months after surgery and chemotherapy is a devastating verdict. Yet for Dr. Cai Songyan, a former regional hospital director, that 2014 relapse became the turning point for a remarkable story of resilience that blends cutting-edge oncology with the ancient wisdom of the Huangdi Neijing (Yellow Emperor’s Classic of Internal Medicine). His ambitious “Anti-Cancer Plate” and strict lifestyle protocol have kept his aggressive lung cancer at bay for over a decade—and turned him into an elite mountaineer.
From Burnout to Breakdown
Dr. Cai’s initial diagnosis of lung adenocarcinoma combined with squamous cell carcinoma was no surprise to those who knew his extreme work schedule. For roughly five years, he juggled the immense pressure of running a regional hospital while pursuing a doctoral degree abroad, leaving him in a state of chronic stress and severe sleep deprivation. The standard treatment—tumor removal surgery followed by chemotherapy—seemed to work, until a follow-up scan revealed a devastating recurrence in the same lung lobe.
The Ancient Wisdom That Changed Everything
Standard Western medicine had hit its limit. Dr. Cai turned to the Huangdi Neijing, where he found a passage that deeply resonated: “The channels of vital energy determine life and death; they treat all diseases and regulate deficiencies. They must not be blocked.”
This shifted his entire outlook. Instead of focusing solely on killing cancer cells, he decided to rebuild his body’s internal terrain—restoring its natural self-healing capacity by optimizing blood circulation, reducing inflammation, and rebalancing his lifestyle.
The “Anti-Cancer Plate”: Three Pillars
Dr. Cai’s daily diet focuses heavily on accessible, high-value ingredients that provide a synergistic defense against cancer recurrence:
- Cruciferous Vegetables: Broccoli, cauliflower, cabbage, and kale are non-negotiable daily staples. These contain sulforaphane, a potent sulfur compound that activates liver detoxification enzymes and helps eliminate free radicals.
- Allium Vegetables: Garlic, onions, and scallions deliver allicin and sulfur compounds with powerful natural anti-inflammatory effects. Research suggests they inhibit angiogenesis—the formation of new blood vessels that feed tumors.
- Mushrooms and Seaweed: Rich in beta-glucan polysaccharides, these ingredients are prized for boosting Natural Killer (NK) cell activity, strengthening immune surveillance against abnormal cells.
Resetting the Metabolism
Beyond specific vegetables, Dr. Cai completely restructured his macronutrient intake to minimize chronic inflammation:
- Low Carb, High Quality Fat: He reduced carbohydrate intake to just 30% of total calories, stabilizing blood sugar and curbing inflammatory spikes. To prevent hunger, he compensates with healthy fats—carrying small bottles of extra virgin olive oil, flaxseed oil, or perilla oil to meals, and snacking on walnuts or macadamia nuts.
- 5 Vegetables, 2 Fruits: A daily target of five servings of vegetables and two fist-sized portions of fruit.
- Omega-3 Focus: Protein sources prioritize fatty fish like mackerel, sardines, and salmon, rich in inflammation-fighting Omega-3 fatty acids.
The 80/20 Principle and the Mountain Climb
Rigid diets often fail due to psychological burnout. Dr. Cai applies an “80/20 Rule”: 80% strict adherence to his health protocol, 20% flexibility for occasional treats like ice cream or soda. This removes guilt and keeps the regimen sustainable.
His daily rhythm is equally disciplined. He wakes between 4:30 and 5:00 AM, exercises outdoors for one to two hours, meditates, and eats his first meal around 8:30 to 9:00 AM—effectively practicing intermittent fasting.
The results speak for themselves. After roughly ten months of this intensive overhaul, Dr. Cai achieved a full decade without cancer recurrence. Even more remarkably, his physical fitness improved to the point where he successfully completed a grueling nine-day traverse of Taiwan’s Central Mountain Range—a feat demanding tremendous endurance.
What This Means for You
Dr. Cai’s journey offers a powerful case study in the Terrain Theory of cancer—the idea that creating an internal environment hostile to malignant cells is just as critical as destroying the cells themselves. While his routine is extreme, the core principles are universally applicable: prioritize sulforaphane-rich vegetables daily, stabilize blood sugar through carb management, and reduce systemic inflammation with quality fats and Omega-3s.

Incorporating just the cruciferous vegetable habit or the 80/20 flexibility rule could be a simple, powerful first step toward building your own defense against chronic disease.
