Low activity by the immune system: This claim asserts that if only the body's immune system were strong enough, it would kill the "invading" or "foreign" cancer. Unfortunately, most cancer cells retain normal cell characteristics, making them appear to the immune system to be a normal part of the body. Cancerous tumors also actively induce immune tolerance, which prevents the immune system from attacking them.
My mom started following an all-natural plan that included vegetable juicing, probiotic foods, immune-boosting supplements, stress reducing techniques and prayer. And after only four months, the tumors on her lungs had shrunk significantly and one year after that, she was again diagnosed as being “cancer-free” and healthy. It’s now been 10 years and my mom recently turned 60 years old — and she is in the best shape of her life, regularly water skiing, running and still going strong.
On the other hand, pathological ketoacidosis is a consequence of other disease conditions such as poorly managed type one diabetes. In this case, the level of ketones will be in the range of 15 to 25 mM. These extremely high levels of ketones can be a serious health problem. The ketogenic diet does not produce this level of ketones. For a thorough discussion of the scientific literature related to the use of the ketogenic diet in cancer treatment I recommend the treatise on the subject by Dr. Thomas N. Seyfried, Cancer as a Metabolic Disease. 
Dr. Brian Peskin also starts with the research of Dr. Otto Warburg on cellular respiration. Dr. Peskin uses the principles of the ketogenic diet in his protocol for cancer treatment. His therapy is a high fat low carbohydrate diet that includes three other aspects. He has found that the standard American diet is highly deficient in certain “parent oils,” which are needed in small amounts to build healthy cells and to provide for proper cell respiration. The absence of healthy oils damages cellular respiration and contributes to cancer formation. He has developed a blend of oils, which provide what the body needs to provide for proper cellular respiration. Also, most Americans are deficient in certain minerals. He uses supplements to provide for these deficiencies. Finally he uses a combination of herbs that are similar to Essiac Tea (described later) to assist with cleansing and detoxification of the body. He presents thoroughly researched evidence that fish oil may not be the best source of omega 3 oils. This makes his research somewhat controversial for some people. His book, The Hidden Story of Cancer, provides extensive scientific documentation of all his claims. Don’t neglect to read the appendices.
Bee Balm was often used by the Native Americans to treat intestinal problems, colic and flatulence. Tea made from this plant was used to induce sweating and break fevers. Bee balm is often used to treat the common cold and sore throat as well. The leaves of this plant are a good source of essential oil that contains thymol. Thymol is an antibiotic and often used as an ingredient in mouthwash.
