Renal cancerPrevention

There is limited experimental evidence that vitamin D can prevent kidney cancer.

There does not exist a serum 25(OH)D level-kidney cancer incidence curve. 

However, a study in Italy found reduced risk of renal cancer for the highest vs. lowest oral intake of vitamin D1.

Based on what is known about solar UVB doses and kidney cancer mortality rates from ecological studies and serum 25(OH)D-incidence relations for breast and colorectal cancer, it appears that maintaining serum 25(OH)D levels above 40 ng/mL (100 nmol/L) might reduce the risk of kidney cancer by 25-35%.
