Every year, millions of people hear the words no one ever wants to hear: “You have cancer.” What follows feels like a sentence: chemotherapy, radiation, and invasive treatments that attack the body as fiercely as the disease itself.
But what if healing could also happen outside of a hospital ward? What if the path to defeating cancer and preventing it could begin right in your kitchen, your garden, and in your everyday choices?
That’s the message at the core of E.R. (Ron) Harder’s groundbreaking book, How to Prevent and Defeat Cancer Naturally. Harder draws on decades of study, observation, and experience as a natural health consultant and offers an eye-opening look at how modern lifestyles have made our bodies breeding grounds for disease. It empowers us to recognize how simple, natural changes can restore the body’s ability to heal itself.
A Wake-Up Call for Modern Health
From the very first chapter, Harder dismantles one of the greatest misconceptions of modern medicine: that disease is random, mysterious, and beyond our control. He argues that illness, including cancer, begins not as an unstoppable genetic accident. He emphasizes that it’s a consequence of how we live, eat, and care for our bodies.
In How to Prevent and Defeat Cancer Naturally, he takes readers step-by-step through how the human body works at its most fundamental level, including the process of digestion, the role of the colon, the pH balance of our internal systems, and the electrical compatibility of the food we consume. His explanation is clear, humble, and refreshingly free of jargon. You don’t need to be a scientist or academic to understand what’s happening in your body, which is a nice change from other medical journals.
He explains that our bodies are electrical systems, finely tuned to the natural energy and balance of the earth. Foods coming through modern farming and processing are chemically altered, genetically modified, or stripped of nutrients. When we consume such foods, we disturb that natural energy. The result? A toxic internal environment where disease thrives.
This isn’t just theory. The author shows readers how the modern food supply, such as chemical fertilizers and GMOs, has systematically weakened the nutritional value of what we eat. Our ancestors, he reminds us, thrived on foods grown in mineral-rich soil and water free of industrial pollutants. Today, we feed our bodies food that looks healthy but is often electrically and nutritionally “dead.”
The cost of that disconnect is staggering: a global health crisis where one in two people is expected to face cancer in their lifetime.
The Missing Link
Harder’s approach is radically simple — and that’s what makes it so powerful. Rather than focusing on symptoms, he looks at the cause: the buildup of toxins and the body’s inability to eliminate them.
In his view, cancer is not an invader, but a warning signal. It’s the body’s attempt to manage toxicity that has nowhere else to go. By restoring balance through proper digestion, a healthy colon, pure water, natural nutrition, and mindful living, we can give the body what it needs to heal itself.
Each chapter of the book builds on this philosophy:
- “The Process of Digestion” reveals how nutrients become energy and how poor food quality disrupts that exchange.
- “Our Food Supply” exposes how industrial agriculture has stripped our food of life-giving enzymes and minerals.
- “The Start of Disease” traces how imbalance and toxicity begin long before symptoms appear.
- “The Workers Within Us” celebrates the body’s remarkable internal systems. This includes the immune cells and natural processes that, when properly supported, can destroy cancer cells on their own.
- “Defeating Cancer” ties it all together, showing how to reverse disease through cleansing, nutrition, and harmony with nature.
The unique qualities that set this book apart are its wealth of insight as well as its tone. Harder doesn’t write like a distant scientist; he writes like a mentor and friend. You will feel like you are reading someone who genuinely believes in empowering you to take control of your health.

Chemotherapy to Common Sense
Harder has been brutally honest about the failures of modern medicine. He doesn’t shy away from questioning the dependence on toxic treatments that often leave patients weaker than before. But unlike so many critics, he provides solutions instead of just pointing fingers.
He believes that healing begins when we realign with the principles Mother Nature built into our very design. For instance, taking simple steps like eating whole, unprocessed foods; drinking pure, mineral-balanced water; and maintaining the body’s natural pH can dramatically shift the way we experience health.
Harder doesn’t view prevention and cure as separate paths. In his eyes, they are one continuous process of nourishing the body so that disease simply cannot take hold.
Why Readers Can’t Put It Down
Readers who pick up How to Prevent and Defeat Cancer Naturally often say it feels like a revelation. It feels as if someone finally connected the dots between what they eat, how they live, and how they feel.
It’s not just a book about avoiding cancer. It’s a blueprint for lifelong wellness, one that empowers readers to make informed choices about food, water, exercise, and even mindset. Harder’s practical advice, which is backed by natural health science and common sense, offers hope to anyone tired of living in fear of disease.
For those who have already been touched by cancer, the book promises clarity and comfort. It reframes cancer not as a death sentence, but as a sign from the body — one that can be understood and answered through natural healing methods.
