Vitamin D deficiency reduces breast cancer survival

Print Friendly, PDF & Email

vitamin-D(NaturalHealth365) The benefits of vitamin D have been connected with an ability to help prevent cancer for years now.  Now, new research is substantiating that high vitamin D levels greatly improve breast cancer survival rate.  Note: Vitamin D blood levels of at least 40 ng/mL or higher have been linked to cancer prevention and lower mortality risk.

In fact, astudy published Nov. 10, 2016 in JAMA Oncology by Roswell Park Cancer Institute and Kaiser Permanente concluded that breast cancer patients with the highest serum vitamin D levels were the most likely to survive the disease.

Optimal vitamin D levels prevent cancer, raise breast cancer survival rate

The study of well over 1,500 women diagnosed with invasive breast cancer were measured regularly for their serum vitamin D blood levels over several years. The readings were measured against health results (secondary cancer, recurrence of breast cancer, and death.) The data was adjusted for possible contributing factors like race, age, socioeconomic status, ethnicity, weight, and tumor characteristics.

The results were clear: study participants with the highest blood levels of vitamin D showed a 30 percent higher breast cancer survival rate than those with the lowest. This effect was magnified in premenopausal women.

The evidence of the role of vitamin D in cancer outcomes and prevention keeps mounting. Other studies have shown that low levels of vitamin D can increase the risk for bladder cancer. A review presented on November 8, 2016 at the annual conference for the Society for Endocrinology in Brighton, England showed vitamin D deficiency to be directly connected with cancer development.

Vitamin D protects against numerous cancer types, contributes to longevity

In particular, bladder cancer recovery and survival rates are markedly improved in persons with higher blood serum vitamin D levels. It is believed that the presence of vitamin D helps to stimulate and support immune system response to abnormal cells that can lead to cancer.

Vitamin D is also associated with the activation of longevity genes.

A UC San Diego study combined data from Grassroots Health and Lappe to assess data related to around 1,300 women. Those with a vitamin D level of 40 ng/mL or higher showed a two-thirds lowered risk of cancer compared with women showing 20 ng/mL or less blood serum vitamin D levels.

This raises concerns, since the current recommended vitamin D level by the Institute of Medicine is 20 ng/mL. Clearly, this should be adjusted to at least double to reap the health-supporting benefits of vitamin D.

Sun exposure, supplementation and vitamin-D rich foods key to health

Vitamin D is best acquired through sun exposure, and in fact regular doses of the sun have been linked with a 70 percent lowered risk for breast cancer. In addition, vitamin D can be taken in supplemental form, and 5,000 to 10,000 IUs per day is often required for optimal blood serum levels.  But, of course, the first step in all of this is to get tested – don’t guess.  And, it’s always best to work with a qualified, healthcare provider – who understands the value of good nutrition.

Speaking about nutrition, the top vitamin D-rich foods are oily fish, mushrooms, soy, tofu, eggs and other dairy foods.  Naturally, when choosing any food – be careful of your food source to avoid unwanted exposure to pesticides, synthetic hormones or any other chemicals.

In addition to fighting and preventing cancer, healthy vitamin D levels can help you reduce the risk of cardiovascular disease, heart attack, hypertension and stroke by about 50 percent. It also boosts the immune system and supports calcium uptake for bone health.

So, the question for you today is: ‘are you getting enough vitamin D – daily?’

    A vitamin D deficiency is implicated is more then this condition. It is such a shame the amount of advertising, which insists you need the strongest suntan lotion to be protected from the sun.

    It would be so much more productive to tell people they need adequate levels of vitamin D. Also, it would be helpful if they told doctors to check their patients’ vitamin D levels.

  • James Kemp

    My doctor never said anything about my vitamin D levels, because he never ordered the test. This is the second time I asked him to include this test.

  • Ronald Lawson

    From my understanding vitamin D is important for the prevention of both colds and flu. No wonder everyone seems to get the flu shot where I live-they have no idea of the alternatives.

  • Libby Reese

    When my mother had this condition the doctor told her to stay out of the sun. It had to do with the chemo they were using in the 1960’s. The doctors still don’t get it and may never get it.

    The American diet depletes us of most nutrients. On top of that the medical agencies are afraid we may be harmed by the sun not the diet.

  • Gregory Bartoni

    People who get lots of sunlight, because of where they live are healthy. Those in northern locations have many more health problems. Why can’t these so called experts add two plus two and realize there is a reason for this?

  • Melony

    I had a friend who had melanoma and never liked the sun. Indoors was her favorite place. It never occurred to the doctors treating her that there was a reason for this disease other then sun exposure.

    Great article, hopefully it reaches everyone that needs it. This is such important information and without it you are at the mercy of doctors. EVERYONE NEEDS TO KNOW WHAT TO DO TO PROTECT THEIR OWN HEALTH.

  • Lucy Albert

    I take a supplement of D3/K2 instead of the calcium recommended by my doctor. There is good reason for this, the supplement my family physician recommends has proven serious side effects.

    When I mention this to him his answer-it is a rare occurrence. When I ask how rare he says quite rare, without any backup statistics. This is not the so-called expert to trust.
