Risco de câncer de pele vs importância da vitamina D – Risk of skin cancer vs importance of vitamin D

Para compensar qualquer perda de produção de vitamina D em razão de evitar o Sol e as suas medidas protetoras (filtro solar impede a produção de vitamina D), os suplementos de Vitamina D poderiam ser disponibilizados prontamente e os países poderiam considerar fortalecer alimentos com vitamina D3.

(…) To compensate for any vitamin D production lost due to sun avoidance and protection measures, vitamin D supplements could be made more readily available and countries could consider fortifying food with vitamin D3.(…)

__

Two recent papers in the British Journal of Dermatology made recommendations on how to reduce skin cancer incidence rates in Europe.1,2 While reducing skin cancer incidence rates is a worthwhile health measure, policies aimed doing so should not compromise overall health.

Ultraviolet (UV) irradiance is the primary risk factor for skin cancer. However, solar UVB is also the most important source of vitamin D for most people, and vitamin D has many health benefits. Thus, measures aimed at reducing skin cancer incidence should be designed in a manner not to reduce vitamin D production from solar UVB irradiance or recommend vitamin D supplements to compensate for reduced vitamin D production from solar UVB.

Skin pigmentation changes throughout the world in response to solar UV doses, striking a balance between protection against folate destruction and the effects of free radical formation on one hand and vitamin D production on the other hand.3 Most Europeans have skin pigmentation well suited to their location due to the long history of civilization in Europe and the relative immobility compared to, say, the United States. Thus, Europeans should not be at high risk for skin cancer.

There is reasonable evidence that skin cancer is associated with better overall health outcomes, likely through higher serum 25-hydroxyvitamin D [25(OH)D] concentrations. A study in Denmark found a 10-year mortality rate ratio = 0.91 (95% CI: 0.89-0.92) for those who developed basal cell carcinoma (BCC), but an increased mortality rate ratio for those who developed squamous cell carcinoma (SCC).4 Smoking is an important risk factor for SCC but only weakly for BCC,5 as well as many adverse health outcomes, which likely explains the different findings.

An ecological study of internal cancer mortality rates with respect to nonmelanoma skin cancer mortality rate in Spain found inverse correlations for mortality rates for 15 types of cancer.6

A study of cancer incidence rates related to 54 categories of occupation using lip cancer standardized incidence ratios (SIRs) less lung cancer SIRs for men as the index of solar UVB dose found this index significantly inversely correlated with 14 types of internal cancer for men and three types of internal cancers for women.5 The evidence that solar UVB reduces the risk of many types of cancer is reviewed in a recent paper.7

There are many types of disease for which vitamin D is protective in addition to many types of cancer. Such diseases include Alzheimer’s disease, cardiovascular disease, diabetes mellitus, and respiratory infections.8,9 Based on calculations of disease outcomes with respect to serum 25(OH)D concentrations, it was estimated that mortality rates in Europe could be reduced by 15-17% and life expectancy increased by 2 years if population mean 25(OH)D concentrations were increased from 54 nmol/l to 110 nmol/l.8 Similar estimates were found for the United States.9  A conference of vitamin D experts meeting in Paris in 2009 recommended serum 25(OH)D concentrations above 75-100 nmol/l.10

Looking at Tables 3-5 in Ref. 1, it appears that outdoor hobbies contribute the most risk for BCC, SCC, and melanoma, followed by outdoor work for BCC and SCC, with sunburns and sunbed use contributing much less risk. However, as found for Nordic countries, outdoor work was very protective against many types of internal cancers for males. As for outdoor hobbies, the best advice would likely be to avoid sunburning, as outdoor hobbies are an important source of vitamin D.

To compensate for any vitamin D production lost due to sun avoidance and protection measures, vitamin D supplements could be made more readily available and countries could consider fortifying food with vitamin D3.

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?

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.

UK – Official new data shows that today’s eggs contain more than 70 per cent more vitamin D and double the amount of selenium than when previous analyses were carried out 30 years ago.

Today’s eggs also contain around 20 per cent less fat, more than 20 per cent less saturated fat, around 13 per cent fewer calories and more than 10 per cent less cholesterol than previous surveys suggested. An average medium egg now contains 66 calories (compared to the previous figure of 78 calories) and an average large egg 77 calories (previously 91 calories).

The data, produced by the UK Foodcomp project consortium, funded by the Department of Health as part of their rolling programme of nutrient analysis surveys, provides the first update on the nutrient content of eggs since the 1980s.

Professor Judith Buttriss, Director General of the BNF, explained: “This is the latest in a series of analyses from the DH-funded UK Foodcomp project that provide up to date information on the composition of the food we eat. These particular data reinforce the contribution to essential nutrients that eggs can make as part of a varied diet, for people of all ages.”

The new analysis, part of which is being presented at The Nutrition Society’s Summer Meeting on 18 July, found that two medium eggs can provide around two-thirds of the RDA (Recommended Daily Amount for EU labelling purposes) for vitamin D. The additional vitamin D found in eggs is particularly significant in the light of evidence suggesting that a large proportion of people in the UK have an inadequate supply of this vitamin.

It has been suggested that, in addition to the well-established role of vitamin D in bone health, this nutrient may also play a role in the immune system and beneficially influence the incidence of some cancers, cardiovascular disease and diabetes.

“This is a very welcome finding at a time when there is rapidly accumulating evidence that a lack of vitamin D could be a risk factor for a number of chronic diseases,” says Cath MacDonald, independent nutritionist.

The increased selenium content of eggs is also of public health significance as UK selenium intakes have declined in recent years alongside a switch from North American to European wheat[4]. Selenium is important in protecting cellular components such as DNA, lipids and proteins against oxidation.

The new analyses reveal that an average medium egg now contains around 177mg of cholesterol, although it is now acknowledged that cholesterol in foods such as eggs does not have a significant effect on blood cholesterol in most people. All major UK heart and health advisory bodies, including the British Heart Foundation, have already removed the previous limits on egg consumption linked to their cholesterol content.

The changes are believed to be the result of improvements to hens’ feed, an increase in the ratio of white:yolk in an average egg, and improved analytical methods since the last official Government analyses were carried out in the 1980s. Vegetable oils replaced meat and bonemeal in UK hens’ feed in the 1980s and it is believed that better quality oils, together with other enhancements to hens’ feed, have improved the hens’ absorption of fat-soluble vitamins and the take-up of nutrients.

Paul Finglas, coordinator of the UK Foodcomp project at the Institute of Food Research, said: “The results from this project are important for monitoring the quality of our national diets through surveys such as the Department of Health’s National Diet and Nutrition Survey, and show the benefits of private:public partnerships working together to support new research projects.”

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!
