To cure cancer, you need to understand the cause and the fundamental cure!
In Oxygen, the Answer for Cancer, Yun describes what cancer is, how it develops and how it is to be cured. Many people commonly think of stress, smoking, oxygen radicals, chemicals, radiation or heavy metals when it comes to the cause of cancer. But this book specifically relates these factors to the direct cause of cancer, which is oxygen deficiency. Also, he introduces some curing ways to cancer, which is to resolve oxygen deficiency by consuming anticancer food like green tea, garlic, and ginseng.
Yun also analyzes how everyday habits can cause or prevent cancer. He disproves commonly-mistaken theories of endless proliferation, inheritance, and spread of cancer cells with logic, experiments and examples. Not only that, he proves the danger of early discovery of cancer, and challenges the modern science with his idea that cancer cells can turn into normal cells. He proposes a new model of cancer cure that protects cancer cells, instead of killing them.
