Until this moment, while the threat of cancer penyaakit specific drugs to stop cancer cell growth has not been found. After all, prevention efforts continue to grown and sitostatika dengaan radiation therapy. But some people prefer alternative therapies. In order to measure the benefits and risks of alternative therapies, it is very necessary understanding of the workings of alternative therapies, including the use of dietary supplements (vitamins, minerals and antioxidants compounds) and herbal preparations that can berkerjaa against cancer.
Various types of food were terbukit contain anticancer substances. Even the stir-fry mix of broccoli, cabbage, cauliflower, carrots, tomatoes and fish meat is very rich in antioxidant elements. Various compounds such as allyl sulfa in garlic, curcumin in turmeric. isoflavones in soy, likofen in tomatoes, polyphenols in green tea, revesratrol in 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-karotein, vitamin C, E, and selenium.
For there are many plants herbal therapies based on empirical experience, it can fight cancer. Among these parasites (dendrophtoe petandra), tread virgin (Catharanthus roseus), meniran (Phyllanthus niruri L), white turmeric (kaempferia ratunda L), tough (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 are two elements that can damage the DNA of normal cells are free radicals and carcinogens. Free radicals can be produced through the metabolism of the body or from the environment around us (gas plants and vehicle exhaust, cigarette smoke, chemicals such as insecticides, chemicals or additives in food). Fortunately, free radicals can be bound and neutralized by several compounds, vitamins and minerals that are antioxidants.
The antioxidant compounds that neutralize free radicals are polyphenols (green tea), likofen (tomatoes), beta-karotein (carrots) and several other compounds in vegetables and fruits. Especially on likofen in tomatoes, is associated strongly with senyawaa fruit fiber. To release, tomatoes must be cooked first with a little oil, given the nature likofen soluble in oil.
Harvard University research terdadap 48 000 1995 oraang paadaa taahun show people who eat 10 times hidangaan yaang contain tomatoes per week aakan decrease the risk of prostate cancer by nearly half. vitamin C, E, and selenium are found in many fruits, vegetables, sprouts, and grains are also a yaang antioxidants neutralize free radicals.
The second element is the carcinogenic substances in food. This substance is actually derived from a procarcinogen by phase I enzymes in the liver is converted into a carcinogen. Meanwhile, phase II enzymes will remove residue prodek phase I enzymes, which can inhibit the formation of cancer cells. If the enzyme phase I enzymes that can be called evil, then the phase II enzymes are enzymes that good.
Phase I enzymes can be inhibited by the compound was allyl sulfides in garlic so that changes can be reduced procarcinogen to a carcinogen. One example of an herb is carcinogenic nitrosamine compounds produced combustion of meat / fish (eg charred skewers) and used cooking oil that has been used many times. Vitamin C plays a role as an antioxidant that inhibits the formation of nitrosamines in the digestive tract.
While the production of phase II enzymes can be enhanced by sulforafan which are often found in broccoli, cauliflower, and cabbage. Therefore, vegetable menu consisting of broccoli, cabbage, cauliflower, carrots, tomatoes, and pan-fried fish a little oil and garlic is one of the menu choices that are rich in antioxidant elements.
If the normal cell DNA damage is also successfully prevented by the compound or vitamin / mineral supplements that are antioxidants, or if already formed cancer cells, actions that we can do is 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 throw him out of the cancer cells, omega-3 fatty acids are abundant in the cold sea fish has an important role. Omega-3 fatty acids are also known as EPA (eicosapentanoic acid) or gamma-lenolenat, is one of the essential fats.
Beberpa types of cancer cells can grow rapidly when triggered by the human estrogen hormones, such as in breast cancer cells. In this case that the isoflavones in soy phytoestrogens was competitive with the human estrogen. So that consumption of soy insoflavon will help inhibit cancer growth induced by the human estrogen. From this we can understand the role of tempeh, tofu, soy milk as a food and prevention of cancer growth.
To inhibit cancer cell metastasis, we need to know how the cell spread. There are two ways air-metastatic cancer cells: Through angiogenesis (new blood vessel formation) and destruction of collagen, which is the framework of normal cells. As such metastases will be inhibited if angiogenesis can be prevented, while the collagen is damaged 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 cox-2 inhibitor preparations which covers resveratrol in red grape skins, turmeric and genestesin krukumin in the soybean. Overhaul of collagen by cancer cells occurs with the help of the enzyme collagenase produced by cancer cells themselves.
Nutritional preparations that can inhibit this process is prombakan vitamin C and shark cartilage. In addition to the formation of interferon merangsaang 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 a megadose of vitamin C.
Forms of other nutrients that can help repair the collagen is shark cartilage is widely touted as a cancer drug. Indeed, shark cartilage is a source of collagen that can provide natural products for body cells to synthetic collagen.
While the flavonoid quercetin in the parasite is expected to work as an inhibitor of cancer cell DNA enzyme (involved in the process of multiplication and increased malignancy of cancer). Tread virgin mind also has two classes of compounds are potent vinca alkaloid inhibits perbaanyakan and spread of cancer cells. Both compounds are vincristine and vinblastine.
In addition the site contains alkaloids catharanthin virgin, which is similar to the compounds in the plasma of cancer cells. The absorption of these compounds is expected to urge and dissolve the cancer cell nucleus.
Meniran and white turmeric plant also has immunomodulatory anticancer properties through his work. The second extract of this plant in the experimental mice was expanding the number of lymphocytes, increases the toxicity of the cancer killer cells (natural killer) and specific antibody synthesis. The properties above will strengthen the body’s defense mechanism against viruses and cancer cells.
Tough leaves are also believed to cure cancer mempunyaai properties for allegedly derived from interferon-like compound that is a natural antibodies against the virus and cancer cells. The way to combat cancer is to destroy 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, rectal, and respiratory tract.
Mintake fungi also as a cancer drug has been studied through a combination of yeast extract with the preparation sitostatika to a number of cancer patients. According to Dr. Iwan T. Budiarso, researchers padaa Balitbang MOH, maitake mushrooms not only relieve the symptoms of breast cancer, lung and liver, but also reduces the effect caused by sitostatika saamping. B 1-6 plosakarida compound in maitake glukans believed to inhibit the growth and spread of cancer cells by increasing the effectiveness of all the cells in the immune system in addition to increasing the sensitivity of cancer cells to sitostatika and radiation.
