Cancer is one of the most fatal diseases that affect a large percentage of the global population every year. Studies have shown that vitamin D plays a critical role in preventing cancer from developing in the body.
This essential nutrient helps in controlling cell growth and division, which is crucial in preventing the growth of cancerous cells.
What is Vitamin D?
Vitamin D is a fat-soluble vitamin that is essential for strong bones and overall good health. It can be obtained through exposure to sunlight or from certain foods such as fatty fish, mushrooms, and fortified dairy products.
The Link between Vitamin D and Cancer Prevention
Mounting evidence from numerous studies shows that vitamin D deficiency increases the risk of certain types of cancer, including breast, prostate, and colon cancer.
According to a study published in the Journal of the National Cancer Institute, high levels of vitamin D in the body can reduce the risk of developing certain types of cancer by up to 50%.
In another study, it was discovered that people with low levels of vitamin D had a higher risk of developing colon cancer than those with adequate levels of the nutrient.
How Does Vitamin D Prevent Cancer?
Vitamin D plays a vital role in regulating cell growth and division. It helps in the differentiation of healthy cells and keeps cancerous cells in check.
When there is an inadequate supply of vitamin D in the body, cell growth can become uncontrolled, allowing cancerous cells to proliferate.
Cancer cells also have a higher rate of replication than healthy cells. Vitamin D helps in inhibiting the rate of cell proliferation, thereby preventing the growth and spread of cancerous cells.

How to Get Enough Vitamin D
The human body is capable of producing vitamin D when the skin is exposed to sunlight. However, people with darker skin and those living in areas with limited exposure to sunlight are at a higher risk of vitamin D deficiency.
Additionally, people with certain medical conditions may not be able to absorb vitamin D effectively, thus requiring dietary supplements.
It is recommended that adults get between 600-800 IU of vitamin D daily. This can be obtained from sunlight exposure, dietary supplements, or through the intake of vitamin D-rich foods such as fatty fish, dairy products, and mushrooms.
When to Speak to a Doctor
If you suspect that you may be vitamin D deficient, it is essential to speak to a doctor. A blood test can be conducted to determine if your vitamin D levels are adequate and whether you need a supplement.
If you have a history of cancer or are at high risk of developing cancer, speak to a doctor about supplementing with vitamin D.
Vitamin D supplements are readily available over the counter, and your doctor can recommend an appropriate dose that will be most effective in preventing the development of cancer.
The Bottom Line
Vitamin D is an essential nutrient that plays a crucial role in cancer prevention. It helps in regulating cell growth and division, which can prevent the growth and spread of cancerous cells.
While vitamin D can be obtained through sunlight exposure, dietary supplements are often necessary for people with certain medical conditions or those living in areas with limited exposure to sunlight.
