Collectively, these early experiments demonstrated that factors specific to the environment of the cell were required to attenuate, or to facilitate, the transforming activity of this potent oncogene. Recent work in transgenic models and specialized cell culture systems has begun to define the specific microenvironmental determinants that have the power to normalize overtly malignant cells.
So when a person has multiple rounds of chemotherapy and everyone is pleased because the tumor is shrinking, do not get too excited because what is usually happening is a killing of the non-stem cell and a production of a more aggressive growing cancer stem cell that is drug resistant. The term is MDR or multiple drug resistance. This is similar to when a person takes too many antibiotics and the bacteria grow stronger and more antibiotic resistant. The same happens with cancer stem cells. This is why people see a shrinking of tumors but then the cancer can return worse than ever before. This is because they did not change the internal environment to make it one that promotes health but instead they tried to kill their cancer cells.
Ground cinnamon is very safe, the volatile oils can however cause a skin rash. Small amounts of coumarin can be found in Cassia and other cinnamons, generally only large doses of this compound will cause blood-thinning and liver problems, but it's something to be aware of. Also if you're planning on having surgery you should stop the use of cinnamon at least one week before going in as it has a blood thinning effect. You should also take care to monitor your blood sugar to avoid an unsafe drop in blood pressure.
Cannabis is a controversial subject, and really needs an article all itself. Few people understand all the political and therapeutic issues surrounding cannabis. Many people distinguish between “medical cannabis” and “marijuana.” Medical cannabis involves research into particular varieties of the cannabis plant and its therapeutic value. Many varieties are lower in THC, the component that makes people “high”, while recreational varieties of marijuana have been cultivated to maximize the amount of THC for recreational purposes.

Mistletoe therapy is the most frequently used complementary treatment in cancer patients in Germany and Switzerland. Iscador was first used for cancer therapy in 1922 by Rudolf Steiner and Ita Wegman based on anthroposophy. (Anthroposophical medicine views the occurrence of cancer, or any illness, as a disease that involves the whole human being, physically, mentally and emotionally.)
Revici Life Science Center, in New York, NY - Emanuel Revici, M.D., until he passed away ran the Revici Life Science Center in NY, NY. Dr. Korin took over until he passed away. It is run for awhile by Dr. Joseph Carozzi. It may now run by Dr. Revici's grandson. They use fatty acids and sterols, enzymes, high-dose selenium, dietary changes, and a "biologically guided" nontoxic chemotherapy. He recommends not taking high dose vitamins without checking how these shift the body's acid/alkaline balance. 212 252-1942
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:
