There is a huge volume of research showing the relationship between vitamin D and cancer. The benefits of this vitamin, or hormone in this regard, apply to both cancer prevention and cancer survival.
Here is a rundown on some of the studies carried out on vitamin D and cancer.
A report which looked at research findings from 1966 to 2004 said that vitamin D can lower breast cancer risk by as much as 50%.
Generally, vitamin D has been widely studied for its benefits on breast cancer prevention. However, more recent research suggests that vitamin D can help improve survival rates as well. Some research revealed that women with low vitamin D levels were more likely to develop more advanced breast cancers compared to those with higher vitamin D levels.
Research carried out over an eight-year period in the 1980s on over 25,000 persons discovered that the colon cancer risk of those with normal levels of vitamin D was a massive 80% lower.
Epidemiological studies have also revealed that higher vitamin D levels could lower colon cancer risk by about 60%.
The Journal of the American Medical Association reported a study involving over 3,000 persons which showed that higher vitamin D and calcium intake was linked to lower rates of colon cancer. Other research studies affirmed this correlation.
Colon cancer is more prevalent in areas of the United States with lower levels of sunshine. This trend is directly linked to vitamin D, as sunshine converts certain chemicals on human skin into the vitamin.cancer ] [ vitamin-d ]
