(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.

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.

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.

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.

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%.

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.

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.

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.

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.

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.

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?

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.

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.

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.

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.

Nowadays, vitamin D is a hot topic both within the medical field and even amongst the general public. Compared to just a decade ago, many more patients are now coming into their physician’s office asking for their vitamin D level to be checked.

The so-called popularity of vitamin D has reached a level such that even people and doctors who do not generally believe in vitamins or supplements have started to jump on the bandwagon of keeping vitamin D levels hearty.

While I am adamantly in favor of using supplements to target various disease states, I am also very conservative in my recommendations of supplements to the patients I see in my clinic of integrative medicine in San Jose, Calif. In other words, I generally subscribe to the concept that vitamins should be treated as medications and thus should always be given with a specific treatment goal in mind and not just haphazardly taken without medical guidance.

Having said this, I am a big fan of vitamin D in general based on the various studies out there in literature. Therefore, I always check that vitamin level in my patients and always aim for a mid-range repletion level. Thus, with such growing popularity about vitamin D, I would like to touch on another study that recently came out in the fall of 2012.

It has long been suggested that vitamn D may help with diabetes management or perhaps even prevention, but a study that came out in the fall of 2012 further affirms us of this notion. In a study of nearly 2,000 individuals, the researchers looked at the serum of individuals who developed Type 1 diabetes mellitus compared to those who did not, and it looks as though people who had deficient vitamin D levels tended toward the development of diabetes mellitus Type 1. Another interesting part of this study suggests that people with a 25-hydroxyvitamin D level of about 50 ng/ml seemed to have lower risk of developing diabetes mellitus Type 1. (3)

Since, in most other studies, achieving a level of 50 is not considered harmful to our health in other ways, it seems that shooting for a 25-hydroxyvitamin D level of 50 ng/ml is a good idea in most patients, especially those with family history of Type 1 diabetes mellitus. (3)

With prior studies suggesting that adequate vitamin D may be beneficial for a diverse array of health issues, including, but not limited to, cancers, diabetes, lung function, and bone health, it is no wonder that patients and doctors alike are making sure that this vitamin level is in the normal range at all times. This study is yet another example of the potential positive health effects of vitamin D. (1-6)

In my clinic, several of my patients have in fact had improvement in glucose control with improvement of their vitamin D level. However, in clinical situations, I also instruct my patients to change their lifestyle habits, including diet and exercise. Therefore ,it is difficult to say whether the lifestyle change alone benefited the patient and/or the addition of supplements.

So, this study was helpful in shedding some light on the situation. Additional lifestyle changes such as diet and exercise were not a factor in this study; the researchers simply evaluated the association between vitamin D level and diabetes. So, based on this study, further support of the idea that vitamin D may be helpful with glucose management is now more clear.

This study may help to explain how some of my patients’ diabetes became better controlled with diet and exercise, but glucose management continued to improve linearly with vitamin D level improvement despite no additional lifestyle changes other than the initial changes made to diet and activity level. It is likely that the lifestyle changes helped their bodies become healthier, but it also seems that the heartier vitamin D levels likely helped their body to become even more efficient in sugar management.

While this study was focused on Type 1 diabetes mellitus, prior studies have also suggested benefits to diabetes mellitus Type 2 when it comes to vitamin D’s benefits for insulin sensitivity and glucose control. (1-6) Despite these encouraging studies, we are still in need of larger scale, randomized, controlled trials to see about the exact benefits and at which dosages of vitamin D might be the most helpful to those with diabetes. For now, this study was helpful in giving an estimation of how much vitamin D repletion is needed to help with diabetes.

While we await larger scale studies on vitamin D and diabetes, I highly encourage the tried-and-true techniques of eating a well-balanced low glycemic load diet and getting in daily exercise to help your body metabolize and function optimally. But if you have diabetes or have a family history of it, I would first caution patients to seek medical advice on diagnosis and management and ask about implementing healthy diet and exercise habits.

You should also ask your physician to check your 25-hydroxyvitamin D level and have your physician aim for a level of about 50 ng/ml. Make sure that your physician monitors your levels and doesn’t just leave you on one dosage without reevaluating you.

Ultimately, we know that we have control over our health… whether it be taking our vitamin D supplements daily or making sure to eat a low-sugar diet and working out daily. So, while the studies are great in helping us understand more about the additional tools we can use to help our body be the healthiest it can be, it is still up to us to do the basics of healthy living… eat what Mother Nature provides for us, as close to its natural form as possible, and keep our body moving every day, because our bodies were made to move and thus we feel our best when we do just that.
