Vit D and Melanoma Protection

Vitamin D, Calcium Supplements May Lower Melanoma Risk For Some Women.

Reuters (6/27, Pittman) reported that taking a vitamin D and calcium supplement may help some women reduce their risk for developing melanoma, according to a study in the Journal of Clinical Oncology. Researchers analyzed medical data from roughly 36,000 women between the age 50 and 79, were randomized to either take both calcium (1,000 mg) and vitamin D3 (400 IUs) supplements or placebo, daily for seven years. The study team found that women who previously had non-melanoma skin cancer were less likely to get melanoma, if they were in the calcium and vitamin D group.

        HealthDay (6/27, Reinberg) reported that the women taking the supplements who had had previous non-melanoma skin cancer reduced their risk of developing melanoma "by 57 percent," compared with women taking the placebo supplements. The study's lead author "speculated that cancer cells lurking in the skin of women who have had a previous skin cancer may be waiting to develop into melanoma. 'But if they take calcium and vitamin D that reduces the risk of developing an actual tumor,' she said." Although the US Institute of Medicine "recommends 600 IU of vitamin D" daily, the findings indicated that as little as 400 IU "may be protective," she added.
