A recent scientific abstract suggests breast cancer risk increases if deficient in the sunshine vitamin, and inversely that vitamin D can therefore prevent breast cancer . Researchers Manar Atoum and Foad Alzoughool published their findings in December 2017 at Sage Journals

The abstract details that the current “worldwide prevalence of vitamin D deficiency is approximately 1 billion.” The fact that 1/7th of the world’s population is deficient in Vitamin D should be alarming as deficiency can be a serious health problem. Previous research has found that diabetes, arthritis, osteoporosis, Parkinson & Alzheimer diseases,  and cancers may all result from vitamin D deficiency.

The researchers noted the inverse relationship between vitamin D concentration and incidence of several cancers, including breast, colorectal, kidney, lung, and pancreatic cancer. They believe a high prevalence of vitamin D deficiency is associated with breast cancer risk, and they set out to learn more about “the relationship between vitamin D level, breast cancer risk, and prognostic factors such as tumor stage, grade, size, lymph node involvement, and hormone receptor status.”

After reviewing available vitamin D studies Atoum and Alzoughool published their abstract which concluded, “most of the vitamin D studies support the inverse association between vitamin D level and breast cancer risk, and retrospective and prospective epidemiologic studies revealed that vitamin D deficiency is associated with increased breast cancer risk.”

With findings such as these, all individuals and parents should be ensuring their selves and family members are not deficient in vitamin D to help prevent cancer and other serious diseases. Current government health regulations suggest only 800 IU of vitamin D should be taken by adults daily if not exposed to the sun for an hour or two (particularly a problem in winter months). However, this amount is to maintain general health, and everyone’s individual needs are different. In fact, your allopathic or naturopathic physician may prescribe a higher daily dose of vitamin D for chronic or acute health conditions.

Currently Health Canada’s Recommended Daily Allowance (RDA) is just 800 IU for adults with 4000 IU being the Tolerable Upper Intake Level. These levels are based on vitamin D for skeletal health only, although the reports of the multitude of other health benefits from maintaining healthy vitamin D levels are known (bone, joint, dental, et al) while ongoing research continues.

Before taking any dose of vitamin D supplementation, or any other medication, please consult your licensed health care provider for diagnosis or testing to determine your individual need.
