Low vitamin D linked to aggressive, advanced prostate cancers

Researchers at Northwestern University's Feinberg School of Medicine in Chicago have conducted a new study suggesting that low blood levels of vitamin D may be linked to more advanced, aggressive cases of prostate cancer in men. According to study author Dr. Adam Murphy, vitamin D "regulates the growth rate of normal cells and cancer cells"; a normal vitamin D level is considered to be in the range of 30-80 nanograms/millilitre (ng/ml). Northwestern University's study, conducted on 667 Chicago men between the ages of 40-79 who were undergoing prostate biopsies, indicates that those who tested positive after the biopsy had very low levels of vitamin D (under 12 ng/ml, thus becoming susceptible to a more aggressive and advanced form of the cancer.
