Dietary vitamin A, beta carotene and risk of epidermoid lung cancer in south-western France.
To investigate the protective role of vitamin A and beta-carotene in lung cancer, 106 patients with carcinoma of the lung and 212 controls were evaluated for their daily vitamin intakes. The study found that lung cancer was associated with a lower consumption of vitamin A and beta-carotene. In conclusion, it was confirmed that vitamin A and beta-carotene have a protective effect against lung cancer. Further details can be found in the study.
