Quick Takeaway: Studies suggest high blood levels of 25-OH vitamin D may prevent melanoma [1] and appropriate D levels may affect the prognosis in both primary [2] and metastatic melanomas. [3] Keep your levels in blood between 50-80 ng/dL.

I would just like to take a moment and talk about children’s cancer. This is not my typical blog about fun and the joy of science and research that I usually strive for.
