Renal cancerTreatment

There is limited evidence from animal and human studies that vitamin D increases survival after diagnosis of kidney cancer.

A study of kidney cancer patients in Japan found serum 25(OH)D levels in kidney cancer patients were lower than those in controls (p< 0.001). Patients with rapid-growth tumors had lower 25(OH)D levels than did patients with slow-growth tumors (p < 0.001)1

Animal studies also found that vitamin D reduced kidney tumor growth rates2

Studies on serum 25(OH)D levels at time of diagnosis of breast3 and colorectal cancer4 found that those with higher levels (>30 ng/mL) had about twice the 12 year survival rate of those with lower levels.
