News in brief: Breast cancer progression slowed with vitamin D
Vitamin D might help slow breast cancer progression, UK research has shown. A study of 279 women with invasive breast cancer showed that the average circulating vitamin D level was 57nmol/l in the 204 patients with early stage disease, compared with 46nmol/l in those with locally advanced or metastatic disease. It remains unclear whether the low vitamin D levels are a cause or consequence of advanced breast cancer, but the researchers say that low levels of vitamin D might promote progression to advanced disease (J Clin Pathol Online).
