Prostate cancer is more aggressive in men with low vitamin D levels, according to a study from the Cleveland Clinic in Ohio. In the 190 men having their prostates removed, those with low vitamin D levels were more likely to have rapidly growing tumors compared to men with normal levels of the vitamin. Blood levels of the vitamin less than 30 ng/mL were associated with increased odds of aggressive disease. The researchers conclude that, “…[the blood vitamin D level]may serve as a useful biomarker in prostate cancer aggressiveness, which deserves continued study.”
