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.
A critical question is often asked: Why pursue the phenotypic reversion of malignancy? Surely it is better to look for more efficient methods of killing tumor cells? Tumors are remarkable creatures, possessed of manifold means to defeat the arsenal of therapeutics arrayed against them. Among other things, the genomic instability of tumors gives them a persistent evolutionary advantage, ensuring the survival of stronger, fitter, more aggressive cells that will go on to populate the body of their host. The approaches that have been taken show that it is possible to revert the malignant phenotype by the correction of environmental cues and by the normalization of signal transduction pathways even as the genome remains malignant and unstable. In this sense, the microenvironment can be dominant over the malignant genotype. It is of course preferable to eradicate the tumor altogether, but aggressive chemotherapy to eradicate a tumor often kills the host. The malleable nature of tumors would indicate that multiple approaches may be necessary. This raises the possibility of the long-term management of some cancers as a chronic condition in which the malignant potential of the tumor cells is constrained, perhaps for the lifetime of the patient.
The next herb on our list is chamomile, this is another great herb with a wide array of uses. The Spanish name for this herb is manzanilla which simply means "little apple" it's no surprise that the Spanish people gave it this name. When the leaves and petals are bruised they give off a very distinct apple aroma. There are two main species chamomile German chamomile and Roman or English chamomile, they're all similar in there medicinal effects but the Roman or English species have a more pronounced aroma than the German variety. Both varieties are relatively easy to grow from seed, in fact if they are left to seed on there own you'll find that they have grown back the next spring.
Ginger is a very popular herb used in cooking, its native to Asia and has been used for over 4,400 years. During ancient times it was used by Indian, Chinese, and Arab medicines. It was so highly prized during the Middle Ages that they thought it actually came from the Garden of Eden. Today you can find ginger being used to treat problems associated with motion sickness. Teas are also made from the root to cure a number of ailments. The Greeks and Romans are probably the first to introduce ginger to Europe at least 2,000 years ago. This probably happened due to trading through the Arabian Peninsula.
I need to say from the very beginning that there are many different ways to approach curing cancer. Some of the treatments involve principles that seem to contradict one another. My goal is to present information that will help you consider alternative treatments, and I will not try to resolve differences in treatment theory. In recent years, I have found the research that supports the validity of the ketogenic diet (which will be discussed first) to be very impressive. It has proven to be a powerful treatment, however, other treatments have been successfully used for curing cancer. My bias is with the ketogenic diet, but I will not deny that many people have also been cured of cancer by using the other methods that will be described even when they did not use the ketogenic diet.
St. John’s Wort is known as Nature’s anti-depressant. It is often used to treat depression and anxiety. It functions as an SSRI (selective serotonin reuptake inhibitor). This allows more serotonin to stay where it’s needed to keep you feeling less depressed and anxious. This herb is also used to help quit smoking. St. John’s work possesses antiviral properties and can be used externally to treat wounds.
About half the practitioners who dispense complementary treatments are physicians, although they tend to be generalists rather than oncologists. As many as 60% of American physicians have referred their patients to a complementary practitioner for some purpose. While conventional physicians should always be kept aware of any complementary treatments used by a patient, many physicians in the United Kingdom are at least tolerant of their use, and some might recommend them.
