High Levels of Vitamin D the “Sunshine Vitamin” Linked to Lower Risk for Breast Cancer
Several recent studies suggest that Vitamin D, the “sunshine vitamin” may help to prevent breast cancer. Vitamin D is called the “sunshine vitamin” because the body produces it after exposure to the sun. Recommended exposure time is 10 minutes. However, many skin doctors today prefer that people get their Vitamin D as a supplement, as there is a danger of contracting deadly skin cancers from too much exposure to radiation from the sun.
New Study from Brazil
A new cross-sectional clinical study from Brazil published in Menopause, September 17, 2018, suggests that post-menopausal women with low blood levels of Vitamin D have a higher risk for developing breast cancer. The study compared 209 women with breast cancer to a control group of 418 women without breast cancer. The women were all post-menopausal ages 45-75 years old.
The women with breast cancer had lower levels of Vitamin D and higher body mass and obesity than the women without breast cancer.
Epidemiological Study of the University of California San Diego School of Medicine
An epidemiological study by researchers at the University of California San Diego School of Medicine in association with Creighton University, Medical university of South Carolina and Grassroots Health were published June 15, 2018 in Plos One. Results of their collaborated research suggest that higher blood levels of Vitamin D are associated with a lower risk for post-menopausal women to contract breast cancer.
Researchers Recommend Higher Blood Levels of Vitamin D than the Currently Recommended Guidelines
There were 3,325 participants from combined studies who were aged 55 or older and who did not have cancer when they enrolled in the study. There were followed from 2002 to 2017 during which time 77 new cases of breast cancer were diagnosed (for an age-adjusted incidence rate of 512 cases per 100,000 person-years).
The researchers and their, principal investigator and co-author Cedric F. Garland discovered that women that had blood levels of more than 60 nanograms per milliliter of the type of Vitamin D commonly found in blood, 25-hydroxyvitamin D (25(OHD), had 1/5 the risk for breast cancer compared to women who had less than 20 ng/ml of 25(OH)D. In fact, the National Academy of medicine that was formerly the Institute of Medicine had recommended in 2010 that women needed to have only 20 ng/ml of 25(OH)D to be considered sufficient in Vitamin D.
To reach the level of 60 nanograms per milliliter a person might have to take 4,000 – 6,000 IU per day. However, no one should take large amounts of Vitamin D without consulting their doctor.
Blood Test to Measure Levels of Vitamin D in the Blood
A simple blood test can show if you have enough Vitamin D. If you are deficient your doctor will tell you how much to take. Dosages of more than 10,000 IU a day can only be taken under strict medical supervision, as too much Vitamin D can be toxic and cause constipation, nausea, heart rhythm problems, loss of weight and kidney damage.
Current Recommended Guidelines
400 IU for children up to one year
600 IU for age 1 to 70 years (including pregnant or breastfeeding women)
800 IU for seniors over age 70
Other studies led by Dr. Cedric F. Garland have shown an association linking Vitamin D to preventing other kinds of cancers such as leukemia, colorectal, multiple myeloma and lung cancers.
Further Research Needed
The researchers suggest that further research needs to be carried out also on pre-menopausal women to see if Vitamin D can also prevent breast cancer in this age group. Also, since the participants in the study were white women, the researchers suggest that other ethnic groups be included in further research.
According to the National Cancer Institute (NCI), breast cancer is the second most common cancer diagnosed for women after skin cancer. The estimated number of new breast cancer cases for 2018 is 266,120. The estimated number of deaths for breast cancer for 2018 is 40,920. Deaths from breast cancer have been decreasing in the United States since 1990.
Cancer is the second most common cause of death in the United States after heart disease.

Since cancer is such a devastating illness, it is to be hoped that increasing blood levels of Vitamin D could lower the risk for many kinds of cancers as well as breast cancer.
