In this meta-analysis, the authors analyzed the association between vitamin D levels and lung carcinoma risk and outcomes (1). Two authors searched various databases using appropriate search terms. High vitamin D intake and levels correlated inversely with lung cancer risk and also reduced lung cancer mortality. High vitamin D helped with survival. The authors conclude that this meta-analysis showed that high vitamin D (or calcium) intake and serum 25(OH)D levels correlate with lower lung cancer risk and better prognosis. UVB and latitude may play a vital role in lung cancer occurrence and progression.
