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.
We live in a world of cancer causing products. They are in conventional food, the water, the air, in our clothing, our automobiles, our homes, the office equipment we use, and in the phones that we use for communication. There is great wisdom in taking reasonable precaution against the factors that can contribute to cancer formation. Sometimes an individual factor may not be a serious risk, but when many factors are combined, they could put a high level of stress on your body and open the door for cancer growth. There are many other factors that could contribute to cancer growth, but the items listed here will be a good starting point.
Survey data about how many cancer patients use alternative or complementary therapies vary from nation to nation as well as from region to region. A 2000 study published by the European Journal of Cancer evaluated a sample of 1023 women from a British cancer registry suffering from breast cancer and found that 22.4% had consulted with a practitioner of complementary therapies in the previous twelve months.

Essiac Tea became popular in Canada and the United States when the herbal tea formula was used by a Canadian nurse to cure many forms of cancer. The formula was given to nurse Rene Caisse by a Native American medicine man. There are various formulas that are now on the market with various names. Most contain the original four ingredients, while others have made additions to the formula.
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:
