Não patenteiem meus genes! Liberem os genes do câncer da mama!

 

Você sabia que as empresas privadas podem patentear genes em seu corpo? Uma empresa chamada Myriad Genetics “possui” dois genes conhecidos como genes BRCA 1 e BRCA2 ou Breast Cancer 1 e câncer de mama 2 . Mulheres com certas mutações nestes genes têm uma forte chance de câncer de mama ou de ovário.Isso tem implicações muito perigosas para a saúde da mulher e da pesquisa científica .O governo não deve conceder às entidades de controle privado algo tão pessoal e fundamental para o corpo humano como nossos genes. Além disso, a concessão de patentes limitam a pesquisa científica, a aprendizagem e o fluxo livre de informação viola a Primeira Emenda.A ACLU argumenta o caso contra patentes de genes perante a Suprema Corte dos EUA em 15 de abril de 2013. Esperamos que uma decisão neste verão.

A empresa Myriad Genetics tem uma patente de dois genes, BRCA1 e BRCA2, ambos intimamente associado com câncer de mama e de ovário. Assim, a Myriad controla a pesquisa sobre os genes, o preço do teste e sua capacidade de obter uma segunda opinião. Patenteamento de genes tem implicações perigosas para a nossa saúde e que recentemente desafiou as patentes sobre BRCA1/BRCA2 no Suprema Corte.  Saiba mais sobre os riscos do patenteamento de genes a partir da perspectiva de um paciente:  https://www.aclu.org/free-speech-technology-and-liberty-womens-rights/patents-human-genes-patients-perspective.

Especialistas médicos criticam a decisão da atriz de promover o exame que detecta os genes BRCA1

 

De famosos a especialistas médicos. Todos deram sua opinião sobre a decisão de Angelina Jolie de submeter-se a uma dupla mastectomia preventiva, já que ela tem uma alta porcentagem de vir a sofrer câncer de mama no futuro.

Mas sua decisão deixou parte do corpo médico bastante preocupado, pois desde que a atriz fez pública sua situação, aumentou consideravelmente o número de mulheres querendo fazer a polêmica cirurgia, mesmo estando saudáveis.

De acordo com o site americano de saúde, Natural Health News, o anúncio de Angelina causou pânico nas mulheres, que acreditam que a mutilação é a única opção para elas.

Mas a companhia denuncia: por trás desse anúncio de Jolie pode estar um negócio bilionário, já que a empresa Myriad Genetics patentou os genes BRCA 1, e agora somente eles, no mundo todo, é que podem fornecer esse exame, que em alguns países, como no Brasil, pode chegar a custar R$ 7 mil.

Médica fala sobre o apoio de Brad Pitt durante as cirurgias de Angelina Jolie
Para o jornalista especializado, da Natural Health, Mike Adams, a decisão de Angelina de dizer ao mundo, não foi nada valente, e sim uma triste forma de aterrorizar as mulheres com falsas estatísticas de câncer de mama, incitando à auto-mutilação e paranoia.

“Angelina Jolie é parte de um astuto plano corporativo desenhado para proteger milhões de dólares em patentes de genes BRCA, e influir na decisão da Corte Suprema dos Estados Unidos”, acusa.

O site financeiro MarketWatch também criticou a atriz:

“Ela simplesmente se nega a dizer a essas mulheres que a cirurgia não é a única opção preventiva, que existe tratamento preventivo, sem ter de tomar essa decisão tão dramática. O que Angelina provocou:

1)  Que mulheres assustadas corressem a fazer esses caros exames por medo, aumentando ainda mais o fluxo da companhia.

2)  Seu anúncio fez com que as ações da Myriard Genetics (MYGN) aumentassem na bolsa. No dia do anúncio, depois da publicação no New York Times, a companhia fechou em alta.

3)  Seu anúncio fez com que a opinião pública influenciasse na decisão da Corte Suprema de Justiça para legislar a favor da privativação dos genes humanos. Angelina Jolie está enganando todas as mulheres do mundo. O que ela fez, literalmente, foi vender as mulheres à indústria do câncer, com fins lucrativos.

4)  As ‘declarações’ de Jolie foram publicadas dias antes de que a Corte expedisse sobre a viabilidade de patentar genes BRCA1″.

E continua:

“Investigadores especializados, conselheiros genéticos, pacientes mulheres, sobreviventes de câncer, instituições de câncer de mama, grupos de saúde das mulheres, e associações científicas que representam a 150 mil geneticistas, patólogos e profissionais de laboratório, argumentam que os genes humanos não podem ser patentados porque são produto da natureza. A intenção de patentar genes humanos viola os exames de diagonóstico e investigação que poderiam conduzir a uma cura, limitando as opções das mulheres com respeito à sua atenção médica”.

Alguns acreditam que a mulher de Brad Pitt também foi enganada. Um médico especialista, consultado pela publicação afirma que todas as pessoas tem microcélulas cancerígenas no corpo, e que algunas desenvolvem a doença, enquanto outras não.

A boa alimentação preventiva, e tratamentos específicos preventivos, podem ajudar mais do que a auto-mutilação.

Câncer de mama: a vitamina D ou mastectomia

“(…) sua forma muitas vezes letal de câncer de mama tende a atacar as mulheres mais jovens e é resistente aos tratamentos existentes , mas Gonzalo e seus colegas agora acreditam que a VITAMINA D poderia ser um tratamento para muitas mulheres com esta forma mortal de câncer de mama. “

Did Angelina Jolie choose the best option for preventing breast cancer? Because having surgery to remove both breasts is a personal choice, we may never have the answer to this question. However, a double mastectomy does not have to be the only choice a woman has.

According to an article in Natural News, investigators for The Journal of Cell Biology, led by Susana Gonzalo, Ph.D., assistant professor of biochemistry and molecular biology at Saint Louis University, ‘… (researchers) have found a molecular pathway that contributes to triple-negative breast cancer. This often deadly form of breast cancer tends to strike younger women and is resistant to existing treatments, but Gonzalo and colleagues now believe vitamin D could be a treatment for many women with this deadly form of breast cancer.’

The research team identified a pathway of molecules in women who are born with BRCA1 gene mutations, which increases their risk for developing breast and ovarian cancers. Tumors grow when the pathway is activated. These tumors don’t respond to standard cancer treatments such as chemotherapy.

It was found that vitamin D turned the molecular pathway off. A study conducted at the German Cancer Research Center with researchers from the University Hospitals in Hamburg-Eppendorf, published in the medical journal Carcinogenesis, showed evidence that women with low blood levels of vitamin D had a much greater risk of breast cancer. In fact, women who had been diagnosed with the most aggressive form of breast cancer had low blood levels of vitamin D.

As many as 1 in 500 women in the US carry the genetic mutation that increases their risk for breast cancer by 60 percent. Even with these high odds against them, women can choose to closely monitor for signs of cancer and begin a regimen of vitamin D supplements.

There have been many recent discoveries in cancer research which give hope to people battling all forms of cancer. We now know about the increased risk of cancer by eating processed meats with sodium nitrates. This includes hot dogs, lunch meats, canned meats, sausage, bacon and frozen meals with meat.

Eating whole foods that have not been genetically altered, fresh organic fruits and vegetables and meat from farms that hasn’t been pumped full of antibiotics and growth hormones is a healthy way to reduce cancer risks. Spicing foods with Turmeric is another way to decrease the risk of cancer.

Although many cures have been found for several types of cancer, they are not well known. For instance, adding vitamin D to your cancer-fighting regimen does not earn money for doctors who make a living treating patients with chemotherapy and radiation. As sad as it is, cancer is a money-making machine. Natural cures are dismissed by the mainstream medical researchers because there is no money in them.

With all of the billions of dollars poured into cancer research in the last 50 years, isn’t it a bit odd that so few cures and treatments have been found? Or have they? There are nearly 100 cancer research institutes in America who operate on donations. If simple, natural cures for cancer were found, thousands of people would be out of a job. It would be counter-productive to find a cure that is safe and affordable.

What do you think? Are there more cures for cancer than we are aware of or do you believe that cancer is destined to be with mankind forever? Please comment and share your thoughts on this subject.

Diversos depoimentos médicos – Vitamin D prevents breast cancer

__

(NaturalNews) You’ve heard the good news about vitamin D for years: It’s a “miracle” medicine that reduces cancer rates by 77% according to previous research

breast_cancer_survivor_pree1

(http://www.naturalnews.com/021892_cancer_Vitamin_D_cancer_industry.ht…). It also happens to be a powerful anti-cancer medicine that can both prevent and help reverse breast cancer.

Yet, bewilderingly, the cancer industry still refuses to teach women about vitamin D. Ever wonder why?

Today, we bring you a compilation of expert quotations on vitamin D and breast cancer, cited from some of the most authoritative books and authors in the world. Feel free to share what you learn here with others who may also be suffering from breast cancer.

Vitamin D and breast cancer

Sunlight triggers the formation of vitamin D in the skin, which can be activated in the liver and kidneys into a hormone with great activity. This activated form of vitamin D causes “cellular differentiation” – essentially the opposite of cancer. The following evidence indicates that vitamin D might have a protective role against breast cancer: Synthetic vitamin D-like molecules have prevented the equivalent of breast cancer in animals.
– The Natural Pharmacy: Complete A-Z Reference to Natural Treatments for Common Health Conditions by Alan R. Gaby, M.D., Jonathan V. Wright, M.D., Forrest Batz, Pharm.D. Rick Chester, RPh., N.D., DipLAc. George Constantine, R.Ph., Ph.D. Linnea D. Thompson, Pharm.D., N.D.

Two equally effective sources of vitamin D in humans are derived from plant ergosterol, which is converted to ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3) by the action of sunlight on the skin. The body uses vitamin D3 for normal immune system function, to control cellular growth, and to absorb calcium from the digestive tract. Vitamin D3 can inhibit the growth of malignant melanoma, breast cancer, leukemia, and mammary tumors in laboratory animals. Vitamin D3 can also inhibit angiogenesis, the growth of new blood vessels that permit the spread of cancer cells through the body.
– Permanent Remissions by Robert Hass, M.S.

There’s surprising new evidence that older women who skimp on foods rich in vitamin D are more likely to develop breast cancer, according to Frank Garland, Ph.D., of the Department of Community and Family Medicine at the University of California at San Diego. This may also help explain fish’s anticancer protection, because fatty fish is packed with vitamin D. Specifically, Dr. Garland finds that dietary vitamin D wards off postmenopausal breast cancer in women over fifty, but not in women who get cancer at younger ages.
– Food Your Miracle Medicine by Jean Carper

In animals fed a high fat diet, which normally would produce a higher incidence of colon cancer, supplements of calcium and vitamin D blocked this carcinogenic effect of the diet. Vitamin D inhibits the growth of breast cancer in culture, and also seems to subdue human breast cancer. Cells from human prostate cancer were put into a “…permanent nonproliferative state”, or shut down the cancer process, by the addition of vitamin D. Human cancer cells have been shown to have receptor sites, or stereo specific “parking spaces” for vitamin D.
– Beating Cancer with Nutrition by Patrick Quillin

Even though vitamin D is one of the most powerful healing chemicals in your body, your body makes it absolutely free. No prescription required. Diseases and conditions caused by vitamin D deficiency: Osteoporosis is commonly caused by a lack of vitamin D, which impairs calcium absorption. Sufficient vitamin D prevents prostate cancer, breast cancer, ovarian cancer, depression, colon cancer, and schizophrenia. “Rickets” is the name of a bone-wasting disease caused by vitamin D deficiency.
– Natural Health Solutions by Mike Adams

George’s Hospital Medical School in London finds local production of vitamin D in breast tissue reduces the risk for breast cancer. For women with low breast tissue levels of vitamin D the risk for breast cancer rose by 354%! This study suggests women sunbathe with breast tissue exposed to the sun to enhance local vitamin D production. The provision of 400 IU of vitamin D per day has been found to reduce the risk of pancreatic cancer by 43%.
– You Don’t Have to be Afraid of Cancer Anymore by Bill Sardi

Taken together, these facts suggest that vitamin D and its derivatives may play a role in regulating the expression of genes and protein products that prevent and inhibit breast cancer. The cancer-stopping power of vitamin D has been documented in osteosarcoma (bone cancer), melanoma, colon cancer, and breast cancer. These cancer cells contain vitamin-D receptors that make them susceptible to the anticancer effects of this vitamin-hormone made by the skin when it is exposed to sunlight. Vitamin D-rich foods include salmon, tuna, fish oils, and vitamin D-fortified milk and breakfast cereals.
– Permanent Remissions by Robert Hass, M.S.

Low levels of vitamin D may also increase the proliferation of white blood cells and may accelerate the arthritic process in rheumatoid arthritis. Vitamin D supplements are likely to be useful in retarding these adverse effects of alterations in metabolism. Low levels of vitamin D have been linked to several cancers including those of the colon, prostate and breast. Laboratory experiments show that vitamin D can inhibit the growth of human prostate cancer and breast cancer cells. Lung cancer and pancreatic cancer cells may also be susceptible to the effects of vitamin D.
– The New Encyclopedia of Vitamins, Minerals, Supplements and Herbs by Nicola Reavley

Laboratory experiments show that vitamin D can inhibit the growth of human prostate cancer and breast cancer cells. Lung cancer and pancreatic cancer cells may also be susceptible to the effects of vitamin D. Sunlight also seems to be protective against several types of cancer including ovarian, breast and prostate cancers; and this effect may be mediated by vitamin D levels. Synthetic vitamin D-type compounds are being investigated for their potential as anticancer drugs.
– The New Encyclopedia of Vitamins, Minerals, Supplements and Herbs by Nicola Reavley

If mutations aren’t corrected or if a cell has already undergone malignant transformation, activated vitamin D can team up with other proteins to stimulate programmed death of abnormal cells. This evidence, along with animal studies, suggest that a girl who lacks adequate vitamin D during puberty years will have abnormal breast development. This, in turn, may increase a woman’s susceptibility to risk factors such as alcohol for breast cancer development. In other words, the window of greatest opportunity for vitamin D to reduce breast cancer risk may be during childhood and puberty.
– The Vitamin D Cure by James Dowd and Diane Stafford

A key development for vitamin D was the appearance of increasing evidence that experts had detected a strong relationship between vitamin D and breast cancer risk. The important Nurses Health Study found a 30 percent lower risk of breast cancer in pre-menopausal women when comparing the highest to the lowest intakes of vitamin D, calcium, and low-fat dairy, especially skim milk.
– The Vitamin D Cure by James Dowd and Diane Stafford

Out of every 100 women who might get breast cancer, 50 of them can avoid breast cancer by simply getting adequate levels of vitamin D in their body, and that’s available free of charge through sensible exposure to natural sunlight, which produces vitamin D. This vitamin, all by itself, reduces relative cancer risk by 50 percent, which is better than any prescription drug that has ever been invented by any drug company in the world. Combine that with green tea, and your prevention of breast cancer gets even stronger.
 Natural Health Solutions by Mike Adams

There’s so much more to vitamin D than enhancing calcium absorption; its anticancer benefit is just one other possibility. Most of 63 recently reviewed studies found a protective effect between vitamin D status and cancer risk. A study presented at the 2006 American Association for Cancer Research meeting suggested that an increase in vitamin D lowered the risk of developing breast cancer by up to 50 percent. How might vitamin D help?
– Food Synergy: Unleash Hundreds of Powerful Healing Food Combinations to Fight Disease and Live Well by Elaine Magee

Place sunshine or vitamin D pills on your list of preventive or therapeutic measures. A daily intake of 2,600 units of vitamin D (65 mcg) is recommended to attain blood concentrations that will optimally protect against disease. There is no way the diet can provide this much vitamin D. Sun-starved females are at great risk for breast cancer, particularly women living in northern latitudes where wintertime sun exposure produces little vitamin D because of a decline in UV radiation in solar light.
– You Don’t Have to be Afraid of Cancer Anymore by Bill Sardi

Sunlight produces vitamin D in humans. A deficiency of vitamin D is linked with breast cancer. Was the increase in male breast cancer caused by magnetic fields or by lack of vitamin D? These are the types of questions that make it difficult to ascertain if there is a link between EMF exposure and cancer. To make matters worse, a cell biologist doing work on EMFs for the Department of Energy, faked data linking cancer to electromagnetic fields in order to gain $3.3 million worth of grants for scientific research.
– You Don’t Have to be Afraid of Cancer Anymore by Bill Sardi

The dosage of vitamin D required to inhibit the growth of prostate cancer may be much higher than the recommended daily allowance (RDA) of 400 international units per day. Since vitamin D can be toxic in doses that greatly exceed this value, researchers have developed synthetic analogues of vitamin D that retain the ability to inhibit cancer cell growth without the toxicity associated with high doses. These analogs have been successfully used in animal models of leukemia and breast cancer. Vitamin D may be related to other cancers.
– Permanent Remissions by Robert Hass, M.S.

Sunlight exposure, which leads to an increased level of vitamin D, correlates with a reduced risk of breast cancer. I usually recommend small amounts of vitamin D (400 to 1,000 IU) for those people without sunlight exposure, especially during the winter. I also occasionally recommend cod liver oil during the winter months as a source of vitamin D and omega-3 fatty acids. Vitamin D deficiency is very common in the elderly and in people who live in parts of the world with little sunlight; it is also one of the major contributing factors to osteoporosis.

But how does vitamin D actually work? For many years that was a mystery. The “revolution of information” on vitamin D began in 1968, when J.W. Blunt and colleagues discovered the form of vitamin D that actually circulates in the blood (25-OH-D3). This hormonal form of the vitamin, created in the kidneys, is ultimately responsible for the classical action of the vitamin. At the molecular level, some cancer cells appear to have receptors on their surfaces that are capable of receiving the vitamin D molecule. Scientists studied cancer cells from 136 patients with breast cancer.

Symptoms of vitamin D toxicity include anorexia, disorientation, dehydration, fatigue, weight loss, weakness, and vomiting. New analogues of vitamin D3 allow cancer victims to take high doses of the vitamin without fear of elevating calcium in the blood to dangerous levels. These new forms of vitamin D have very high potency in controlling cell proliferation and differentiation. One of these, calci-potriol, can be used topically to treat psoriasis and inhibit the growth of metastatic breast cancer in patients with whose tumors have vitamin D receptors.
– Permanent Remissions by Robert Hass, M.S.

In an investigation into the relationship of breast density as measured by mammography to serum-vitamin D levels, it was found that there was a strong inverse correlation; the higher the density, the lower the vitamin D levels. Does the blood level of vitamin D at the time of diagnosis of breast cancer make a difference in a woman’s time of survival? Yes, it does.
 The Clinician’s Handbook of Natural Healing by Gary Null, Ph.D.

Although not part of the study, outdoor exercise where you are getting some (but not too much) sun exposure also raises vitamin D levels. Low levels of vitamin D have been associated with a greater risk of cancer. Relaxation techniques such as writing, meditation, yoga, or massage therapy can aid in battling breast cancer. There is a clear link between alcohol consumption and an increased risk of breast cancer. A study reported in The New England journal of Medicine has stated that consuming as few as three alcoholic drinks a week increases the potential for breast cancer by 50 percent.

Deficiência de vitamina D aumenta risco de doenças cardiovasculares

Estudo feito em pessoas com baixos níveis da vitamina mostra que elas são 81% mais propensas a morrer de doenças do coração.

Vitamina D – Sem Censura – Dr. Cicero Galli Coimbra e Daniel Cunha

__

Cientistas da Universidade de Copenhague, na Dinamarca, descobriram que baixos níveis de vitamina D estão associados a um risco significativamente maior de ataque cardíaco e morte precoce.

O estudo, que envolveu mais de 10 mil dinamarqueses, sugere que a deficiência da vitamina causa aumento da pressão arterial.

A deficiência de vitamina D tem sido tradicionalmente associada a problemas de saúde óssea. No entanto, resultados de estudos populacionais anteriores indicam que um baixo nível de vitamina esta importante pode também estar ligado a um maior risco de doença cardíaca isquêmica, que abrange ataque cardíaco, arteriosclerose coronária e angina.

A equipe comparou os níveis de vitamina D em amostras de sangue de 10 mil dinamarqueses de 1981 a 1983. Os participantes foram seguidos nos registros nacionais até a data atual.

“Nós examinamos a associação entre baixo nível de vitamina D e o risco de doença isquêmica e morte no maior estudo até à data. Observamos que pessoas com baixos níveis da vitamina são 40% mais propensas a doença cardíaca isquêmica, têm um risco 64% maior de ataque cardíaco e 57% maior de morte prematura. Os resultados mostraram ainda que elas são 81% maio propensas a morrer de doença cardíaca”, afirma o pesquisador Peter Brøndum-Jacobsen.

Segundo o autor sênior, Børge Nordestgaard, com este tipo de estudo populacional, não é possível dizer qualquer coisa definitiva sobre uma possível relação causal. Mas é possível afirmar que há uma forte correlação estatística entre um baixo nível de vitamina D e o alto risco de doença cardíaca e morte precoce.

Agora, a equipe está trabalhando agora para determinar se a ligação entre o baixo nível de vitamina D e o risco de doença cardíaca é uma relação causal. Se isto for verdade, então, eles esperam causar uma mudança no padrão de prevenção da população mundial.

“A forma mais barata e fácil de obter quantidade suficiente de vitamina D é a exposição ao sol em intervalos regulares. Há muitas evidências de que o sol é bom, mas também é importante evitar ficar muito exposto, o que aumenta o risco de pele câncer”, conclui Nordestgaard.

New research may start to shed light on why Marin County has one of the highest rates of breast cancer in the world, and the answer may be related to vitamin D.

A small pilot study of Marin County women determined through testing to be at high risk for breast cancer found them to be almost twice as likely to have a variant of a vitamin D receptor as the overall population of 338 in the study.

Researchers have long been investigating and discovering variations in genes that could be associated with breast and other cancers. This is the first time a study has linked this vitamin D receptor – a protein molecule that signals the cell to activate vitamin D – with higher risk for breast cancer in Marin County women, the authors said.

Additionally, numerous studies have found a relationship between adequate vitamin D in the body and a lower risk of cancer.

“A lot of people have been doing analyses of vitamin D levels and breast cancer risk, but there haven’t been a lot of studies addressing the vitamin D receptor itself,” said Dr. Kathie Dalessandri, a surgeon scientist in Point Reyes Station and primary author of the study.

“I think this is just the tip of the iceberg,” she said, adding that the findings need to be validated in a larger study.

A focus on Marin

Researchers have long been trying to determine why largely white, affluent Marin County has higher than average rates of breast cancer.

Studies have looked at traditional risk factors such as age at the time of diagnosis, age at giving birth for the first time, family history of breast cancer and use of hormone replacement therapy. But none has offered any clear conclusions.

The first major study to look at these issues, which was led by UCSF researchers and published in 2003, determined there was nothing about the land itself in Marin County that appeared to cause breast cancer. It concluded that a woman’s risk of developing the disease did not increase according to the amount of time spent in the county.

While researchers have focused on the levels of vitamin D in the body and the vitamin’s potential to lower risk of breast and other cancers, they have yet to determine the role of vitamin D or how much of it is needed for cancer prevention.

In this most recent study, which was published online this week in the Journal of the American College of Surgeons, the role of the variant in the vitamin D receptor and how that affects the amount of vitamin D in the body is also unclear.

The variant “is known to be associated with differing vitamin D levels, but the exact way it works is not known, which is kind of frustrating,” said Eldon Jupe, clinical laboratory director of InterGenetics Inc. and developer of the breast cancer risk test that was used in the study. “But it does give a direction in which to look.”

Researchers used cell samples taken from the mouths of 338 women from the 2003 UCSF study.

A larger study pool

A larger, collaborative study in Marin County is ongoing, headed by the Marin County Department of Health and Human Services. The breast cancer study, called the Marin Women’s Study, involves thousands of women. Investigators hope this study group could be used to advance the vitamin D receptor research.

Rochelle Ereman, director of the Marin Women’s Study, said Dalessandri’s research “provides us another possible piece to the puzzle as to why Marin’s breast cancer rates have been historically high.”

Jeanne Rizzo, president of the Breast Cancer Fund, an advocacy group that focuses on the environmental causes of breast cancer, said it’s too soon to stock up on vitamin D.

“But this tells us we should be looking at things that are not just traditional risk factors and it’s important to continue this investigation,” said Rizzo, who is also a Marin County resident.

Vitamina D – por uma outra terapia

A new study published this month finds that the hormonally active form of vitamin D, Calcitriol 1,25-dihydroxyvitamin D(3), inhibits the growth of many kinds of cancerous cells, including breast cancer, indicating that vitamin D3 can be useful in treating and even preventing a variety of cancers. Authors of the study said that caner cell growth is inhibited by “anticancer actions including cell cycle arrest, promotion of apoptosis and inhibition of invasion, metastasis, and angiogenesis.” Vitamin D’s anti-inflammatory properties and interference with estrogen synthesis further explains its anti-tumor properties.

Two studies from 2007 used meta-analysis, which combines data from multiple reports, to find that therapeutic doses of vitamin D could prevent up to half of all cases of breast cancer, and two-thirds of all cases of colorectal cancer in the United States. The studies showed a direct correlation between blood levels of vitamin D and cancer. Those with the highest blood levels were found to be at the lowest risk, and the lowest blood levels at the highest risk.

Many sources still try to cast a shadow on the effectiveness of vitamin D, citing that a specific dose strength has not yet been established, and needs more research. It likely won’t be narrowed down to a one-size-fits-all dose, because every body is different, and if it were, it wouldn’t be as effective. One other thing that may be giving varied results regarding dosing is the source of vitamin D used – it varies from study to study. Typically, higher doses are required of synthetic sources to increase blood levels, and they don’t generally have the same effect as natural sources.

The “sunshine” vitamin, vitamin D is fat-soluble vitamin required for the absorption and utilization of calcium and phosphorous. It protects against muscle weakness, regulates heartbeat, is necessary for normal blood clotting and thyroid function, and regulates more than 2,000 genes, affecting the proliferation and death of cells.

Vitamin D comes in several forms. The kind that comes from food is D2. There is a synthetic form, D5. The most active is the most natural kind, D3. It is synthesized in the skin in response to the sun’s ultraviolet rays. There is a cholesterol compound in the skin that is a precursor of vitamin D. The D we get from food and supplements is not fully active until it goes through the liver and kidneys, where it is converted, then it circulates through the blood like a hormone.

According to Bach, problems from deficiency may include: heart disease, birth defects, depression, hypertension, stroke, dementia, fibromyalgia, impaired bone mineralization, skin, breast, prostate and other cancers, multiple sclerosis, insomnia, eye problems, problems with pregnancy, and other chronic diseases. It is estimated that more than one billion people worldwide, and 77 percent of Americans, are deficient in vitamin D.

It is not possible for most people to consume enough vitamin D thorough diet alone. It is found in fatty saltwater fish and fish liver oils, such as halibut, salmon, sardines, and cod liver oil. It is also added (fortified) to diary and eggs, so you’ll find it in things like milk, yogurt, and butter. Other foods that have vitamin D include dandelion greens, oatmeal, cereals, and sweet potatoes.

Having a healthy and balanced diet can prevent cancer, and the need for prescriptions that contribute to cancer, such as cholesterol reducing drugs that inhibit vitamin D absorption from the sun. Even the National Cancer Institute estimates that 80 percent of cancer cases could be prevented. Most people supplement to get enough vitamin D. The recommended doses are generally not enough to address health problems. Be sure your supplements come from whole food vitamins so that higher doses won’t be detrimental to your health, as they might from synthetic vitamin sources.

Eating good food, limiting unhealthy food and substances, getting exercise, and soaking up a bit of sun are critical to happiness and lasting health. So get out there and have fun – and help prevent cancer while you’re at it!
