Introducing Vitamin D is an easy way to slash your cancer risk

Written by

More than three-fourths of people with a variety of cancers have low levels of vitamin D, and the lowest levels are linked with more advanced cancers, a new study suggests.

High-dose supplements increased vitamin D levels to normal in most patients studied.

Studies propose that vitamin D has anti-tumor properties, regulating genes implicated in the growth and spread of cancer cells. The five most common diagnoses were breast, prostate, lung, thyroid, and colorectal cancers.

Among people in the study, 42% had vitamin D insufficiency.

Researchers studying the preventive effects of vitamin D on cancer have proposed a new model of cancer development that hinges on a loss of cancer cells' ability to stick together. The model, nicknamed DINOMIT, differs from the older model of cancer development, which proposes genetic mutations as the first driving forces behind cancer.

"The first event in cancer is loss of communication among cells due to, among other things, low vitamin D and calcium levels," said epidemiologist Cedric Garland. "This loss may play a key role in cancer by disrupting the communication between cells that is essential to healthy cell turnover, allowing more aggressive cancer cells to take over."

Garland suggests that such cellular disruption could account for the earliest stages of many cancers. Previous theories linking vitamin D to certain cancers have been tested and established in more than 200 epidemiological studies.

Each letter in DINOMIT stands for a different stage of cancer development – disjunction, initiation, natural selection, overgrowth of cells, metastasis, involution, and transition.

Garland suggests that much of the evolutionary process in cancer could be arrested at the outset by maintaining adequate vitamin D levels.

One recent large-scale, randomized, placebo-controlled study on vitamin D and cancer showed that vitamin D can cut overall cancer risk by as much as 60 percent! This was such groundbreaking news, the Canadian Cancer Society has actually begun endorsing the vitamin as a cancer-prevention therapy.

Similar results were shown in another study investigating vitamin D's impact on breast cancer. It discovered that light-skinned women who had high amounts of long-term sun exposure had half the risk of developing advanced breast cancer (cancer that spreads beyond your breast) as women with lower amounts of regular sun exposure.

Vitamin D levels can slash your risk of cancer by as much as 60 percent. Keeping your levels optimized can help prevent at least 16 different types of cancer, including pancreatic, lung, ovarian, prostate, and skin cancers.
