Vital Signs for Cancer Prevention suggests that cancer is a two-phase process. In Phase One you do not yet have, and may never have, cancer, but predisposing factors—poor diet and digestion, toxins, adrenal exhaustion, and blood sugar imbalances, among others—can progressively and cumulatively increase your likelihood of developing it. Phase Two begins when the first permanent, transformed or cancerous cells form and are not destroyed by your defenses. Understanding that the predisposing factors of the first phase lead toward the second can help you prevent the onset of cancer by correcting or minimizing those that apply to you.
 
Author Xandria Williams takes a natural therapies approach to healing cancer—one based on an understanding of nutrition, herbal medicine, homoeopathy, osteopathy, and energy medicine—rather than one based strictly on medicine, drugs, and surgery. She sees cancer as a problem that affects the whole body, not just the organ or system that is faulty, and thus her recommendations are systemic rather than aimed specifically at the tumor. Her main emphasis is on a series of scientifically validated tests (many of which can be self-administered) she proposes that provide vital information as to the state of your health. She also describes the CA profile, a test that can indicate the presence of permanent cancer cells within the first six weeks and possibly years before a tumor can be detected, allowing a crucial warning and the time to start an effective recovery program. Williams suggests a number of supplements, specific foods, and other remedies (detox procedures, stress reduction) to correct any of the predisposing factors that could, with a final trigger, move you from Phase One to Phase Two of the cancer process.
