Sun Exposure Linked to Lower Lung Cancer Risk

For years, doctors have professed the dangers of sun exposure and studied the links between UV radiation and skin cancer, but researchers are now exploring the cancer fighting properties of moderate daily sun exposure. Data from 111 countries worldwide indicate that lung cancer rates are highest in countries furthest from the equator, where sun exposure is lowest. Regions nearest the equator report the lowest rates of lung cancer. Sunlight promotes vitamin D production in humans, and researchers believe that this vitamin plays a vital role in halting tumor growth.
