Until this moment a threat of cancer, while the specific drugs to stop cancer cell growth has not been found. After all, prevention efforts continue to be tried with radiation therapy and sitostatica.
However, some patients prefer alternative therapies. In order to measure the benefits and risks of alternative therapies, much needed understanding of the workings of alternative therapies, including the use of dietary supplements (vitamins, minerals and antioxidant compounds) and herbal preparations that can work against cancer.
Various types of food was shown to contain anticancer substances. Even broccoli stir-fry mix, mustard greens, cauliflower, carrots, tomatoes, fish and meat is very rich with antioxidants element.
Various compounds such as allyl sulfides in garlic, curcumin in turmeric, an isoflavone in soy, likofen in tomatoes, polyphenols in green tea, revesratrol in the skin of red grapes, and broccoli is a food sulforafan in cancer prevention. Some vitamins and minerals is also an antioxidant that is often promoted for cancer prevention: beta-carotene, vitamin C, E, and selenium.
For herbal therapy, there are many plants that based on empirical experience, it can fight cancer. Among these parasites (Dendrophtoe petandra), vinca (Catharanthus roseus), meniran (Phyllanthus niruri L), white turmeric (Kaempferia rotunda L), strong (Pettiveria alliacea) and maitake mushrooms (Grifola frondosa).
Cancer appears when normal cell DNA damage, causing genetic mutations. If this is not immediately corrected, the multiplication of cells that DNA damage is a potential to produce cancer cells. Yet the multiplication of cells intended for the recovery of cells that are worn or damaged.
In terms of nutrition, two elements that can damage the DNA of normal cells are free radicals and carcinogens. Free radicals can be generated through metabolism or from the environment around us (plants and vehicle exhaust, cigarette smoke, chemicals such as insecticides, chemicals or additives in food). Luckily, free radicals can be bound and neutralized by several compounds, vitamins and minerals that are antioxidants.
The antioxidant compounds that neutralize free radicals, polyphenols (green tea), likofen (tomatoes), beta-carotene (carrots), and several other compounds in vegetables or fruit.
Especially on likofen in tomatoes, this compound strongly bound by fiber fruit. To free him, tomatoes must be cooked first with a little oil, given the nature likofen which easily soluble in oil.
Harvard University study of 48,000 people in 1995 showed that people who eat 10 times the dishes that contain tomatoes per week would decrease the risk of prostate cancer by almost half. Vitamin C, E, and selenium are widely available in fruits, vegetables, sprouts, and grains also is an antioxidant that neutralizes free radicals.
The second element is carcinogenic substances in food. This substance is actually derived from prokarsinogen that by phase I enzymes in the liver is converted into carcinogens. Meanwhile, phase II enzymes will remove product residue phase I enzymes, which can inhibit cancer cell formation. If the enzyme phase I enzymes that could be called evil, then the phase II enzymes is an enzyme that good.
Phase I enzyme was found to be inhibited by compounds in garlic allyl sulfides so that changes can be reduced prokarsinogen be carcinogens. One example is the famous carcinogen nitrosamine compounds produced by combustion of meat / fish (eg charred skewers) and used cooking oil that has been used many times. Vitamin C acts as an antioxidant that inhibits the formation of nitrosamines in the digestive tract.
While the production of phase II enzymes can be increased by sulforafan which are often found in broccoli, cauliflower, and mustard greens. Therefore, the menu consists of vegetables broccoli, cabbage, cauliflower, carrots, tomatoes, and fish sauteed a little oil and garlic is one of the options menu that is rich in antioxidants element.
Pressing Cancer Cell Growth
If DNA damage in normal cells fails again prevented by the compounds or vitamins / minerals that are antioxidants, or if already formed cancer cells, the actions that we can do is to suppress the growth of cancer cells. Rapid growth of cancer cells after the cells are getting omega-6 fatty acids. To reduce the influence of these fatty acids as well as away from the cancer cells, omega-3 fatty acids are widely available in the cold sea fish have an important role. Omega-3 fatty acids are also known as EPA (eicosapentanoic acid) or gamma-lenolenat, is one of the essential fats.
Some types of cancer cells also can grow rapidly when triggered by the human hormone estrogen, such as in breast cancer cells. In this case, which is a phytoestrogen isoflavones in soybeans was competitive with human estrogen. So that consumption of soy isoflavones will help inhibit cancer growth induced by estrogen humans. From this we can understand the role of tempeh, tofu and soy milk for food prevention of cancer growth.
To inhibit metastasis of cancer cells, we need to know how these cells to spread. There are two ways air-metastasis of cancer cells: through angiogenesis (the formation of new blood vessels) and the destruction of collagen which is the framework of normal cells. Thus, metastases can be inhibited if angiogenesis can be prevented, while the damaged collagen can be repaired by the body itself to take advantage of certain foods.
For angiogenesis, cancer cells release growth factors. Production of growth factors was found to be inhibited by the cox-2 inhibitor preparations that includes resveratrol in red grape skins, curcumin in turmeric and genestein in soybean.
Overhaul of collagen by cancer cells occurs with the aid of collagenase enzymes produced their own cancer cells.
Preparations nutrients that can inhibit the process of this reshuffle is vitamin C and shark cartilage. In addition to stimulating the formation of interferon join the fight against cancer cells, vitamin C was able to repair damage to collagen by creating new collagen by proline hydroxylation. Perhaps this is what underlies the role of controversial statements from a nobel prize winner in chemistry and peace, Linus Carl Pauling, regarding nutrition therapy of cancer with vitamin C megadose.
Forms of other nutrients that may help repair cartilage collagen was sharks that much touted as one of the cancer drug. Indeed, shark cartilage is a source of collagen that can provide natural materials for the body's cells to synthetic collagen.
Herbal Therapy
Flavonoid quercetin in the parasite is expected to work as an inhibitor of cancer cell DNA isomerase enzyme (involved in the process of multiplication and increased malignancy of cancer). Vinca compounds are known also to have two classes of potent alkaloid Vinka inhibit the multiplication and spread of cancer cells. Both compounds are vincristine and vinblastine.
In addition, vinca alkaloids contain catharanthin, which is similar to compounds in the plasma of cancer cells. Absorption of these compounds into cancer cells is expected to urge and dissolve the cancer cell nucleus.
Plants meniran and white turmeric also has anticancer properties through its immunomodulatory work. The second extract of this plant in experimental mice turned out to multiply the number of lymphocytes, increase the toxicity of cancer killer cells (natural killer) and specific antibody synthesis. The properties above will strengthen the body's defense mechanism against viruses and cancer cells.
Leaf is also thought to have powerful healing properties because of suspected cancer-like compounds derived from interferon which is a natural antibodies against viruses and cancer cells. How to combat cancer by destroying cancer-causing virus that can damage the DNA of normal cells into cancer cells. Tough leaves are said to more efficacious for this type of prostate cancer, rectum, and respiratory tract.
Maitake mushrooms as a cancer drug had been studied by a combination of mushroom extract with preparations sitostatica to a number of people with cancer. According to Drs. Iwan T. Budiarso, a researcher at the Research and Health Department, maitake not only alleviate the symptoms of breast cancer, lung and liver, but also reduce side effects caused by sitostatica. Compounds 1-6 plosakarida B glukans believed to play a role in maitake inhibits the growth and spread of cancer cells by increasing the effectiveness of all cells in the body's defense system in addition to increasing sensitivity of cancer cells against sitostatica and radiation.
