Scientists don’t know for sure. Since chemotherapy and radiation kill cells that divide often, stem cells may be less vulnerable because they rarely divide. Some scientists believe cancer stem cells may have genetic mutations that make them resistant to damage from chemotherapy or radiation, or cancer stem cells may be able to repair DNA damage more rapidly than normal cells.
Over several decades, our understanding of the pathogenesis of neoplasia has been advanced tremendously. Many oncogenes and tumor suppressor genes have been identified and characterized, and it is usually accepted that cancer is a genetic disease. Nevertheless, it is beginning to be appreciated that the interrelationships between the tumor epithelium and the tissue microenvironment play a critical role in tumorigenesis. It has been demonstrated the ability of the tissue microenvironment to control malignancy and the mechanisms of tumor initiation, progression and regression.
When we realize that fear is controlling us, we can turn away from the grip of conventional cancer treatment and make other choices. Some people turn to alternative cancer treatments after it has become clear that conventional treatments are not working. Other people just skip conventional treatments altogether and go directly to safer alternatives.
Integrative Health Care, PC, in Scottsdale AZ, is run by Alan Christianson, ND treats almost any type of cancer, even later stage cancers. They use metabolic therapies for those not undergoing conventional care. For those doing conventional treatments, they use intravenous nutrition and botanical meds to prevent side effects and help efficacy of chemo/radiation.

The pharmaceutical cartel is so threatened by this treatment that the US government filed twelve patents on the use of antineoplaston even though Dr. Burzynski already had filed his own patents many years earlier. Dr. Burzynski is still trying to get his treatments approved by the FDA, but it is currently not approved. A film has been made documenting his remarkable discoveries in cancer treatment, and his battle against the Texas Medical Board and the US FDA (see trailers below).
James R. Privitera, M.D. has an office in Covina. He treat arthritis, circulatory problems, preventive medicine, chronic fatigue, and PMS in addition to cancer. His approach is to use nutrition, immunological enhancement, chelation, and darkfield microscope. His website is http://www.nutriscreen.com/.

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.

Eating a clove or two of fresh garlic a day may indeed keep the doctor away, in part because it has immune-boosting, antibacterial, antiviral, and anti-fungal effects. Many of garlic's therapeutic effects are derived from its sulfur-containing compounds, such as allicin, which are also what give it its characteristic smell. In general, garlic's benefits fall into four main categories:
