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.

The aptly named bitter melon is thought to help cells use glucose more effectively and block sugar absorption in the intestine. When Philippine researchers had men and women take bitter melon in capsule form for three months, they had slight, but consistently, lower blood sugar than those taking a placebo. Gastrointestinal problems are possible side effects. You can reverse diabetes with these science-backed strategies.
Chemical compounds in plants mediate their effects on the human body through processes identical to those already well understood for the chemical compounds in conventional drugs; thus herbal medicines do not differ greatly from conventional drugs in terms of how they work. This enables herbal medicines to be as effective as conventional medicines, but also gives them the same potential to cause harmful side effects.[1][2]
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.

Researchers found that the ketogenic diet significantly decreased blood glucose, slowed tumor growth, and increased mean survival time by 56.7% in mice with systemic metastatic cancer. While hyperbolic oxygen therapy by itself did not influence cancer progression, when it was combined with the ketogenic diet, it produced a significant decrease in blood glucose, tumor growth rate, and a 77.9% increase in mean survival time compared to controls.

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.[7] 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.[10]


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:
