An analysis conducted by european universities has shown that having adequate levels of vitamin D in the blood could be associated with a lower risk of developing certain cancers.
A team of scientists from the university of Eastern Finland and the autonomous university of Madrid has reviewed updated information regarding vitamin D and the role it plays in cancer prevention. The study has been taken up in the journal Seminars in Cancer Biology.

Beneficial in the prevention of several cancers
The article states that the various studies that have looked at the the effects of this vitamin on different types of cancers suggest that a “good“level of vitamin D in the blood may be particularly beneficial for reducing the prevalence of colorectal cancer, leukemias and lymphomas. The level is too low vitamin D has also been associated with an increased risk of breast cancer and prostate cancer. In addition, it would appear that low levels of vitamin D in the blood is linked to a higher risk of cancers and forecasts more pessimistic.
The researchers explain that vitamin D is necessary for the proper functioning of blood cells and regeneration rapid tissue of adult cells.
If the levels of vitamin D are too low, the cells function less optimally, and can potentially becoming cancerous.

Not all equal in the face of vitamin D needs
The science team also notes that the identified randomized controlled trials that focused on the role of supplements of vitamin D could reduce the mortality of cancer have reached conflicting results. The authors explain that the role of vitamin D might be more clear if the studies took into account the responsiveness to individual vitamin D, that is, the molecular response or sensitivity of each face of the supplements of vitamin D.
They add that a strong responsiveness to vitamin D may be associated with a lower risk of cancer. The responsiveness to vitamin D varies depending on the individual and affects their needs in add-ins of vitamin D. For example, 25% of the Finnish population appears to be weakly reactive, the researchers explain, and thus would need a higher dose of this vitamin.
It is possible to measure his level of vitamin D with a blood test. A level of 20 nanograms/ml to 50 ng/mL is considered suitable for people in good health. A level of less than 12 ng/mL indicates a vitamin d deficiency.
