Keeping serum 25-hydroxyvitamin D levels above 40-60 ng/mL would reduce risk by 15-25% and increase survival after diagnosis.
Kidney (or renal) cancer affects 61,000 Americans annually and kills 13,000 1.
It is one of the approximately 20 vitamin D-sensitive types of cancer.
Evidence from ecological (geographical) studies of renal cancer mortality rates are lower in areas where people have more exposure to solar ultraviolet B radiation.
Based on analogy with the geographical variation of breast cancer mortality rates, it seems that keeping serum 25-hydroxyvitamin D levels above 40 ng/mL (100 nmol/L) might reduce risk by 15-25% and increase survival after diagnosis.
Known risk factors for renal clear cell cancer are obesity, smoking, hypertension and male gender2 3 and increased risk of renal cancer has also been linked to exposure to chemicals such as pesticides4 and diet high in animal products2.
