Vitamin D Levels Linked to Aggressive Breast Cancer

A recently published study finds low blood levels of vitamin D may promote more aggressive breast tumors.

The relationship between between low vitamin D levels and higher risk of developing breast cancer has been previously documented in numerous studies. Women with inadequate intake of Viamin D or with low blood levels (below 55ng/ml) have very poor prognosis and higher risk of metastatic disease and death from breast cancer.
