Scientists have discovered that men who get to little sun have increased risk to get cancer in the prostate compared to men who gets a lot of sun. The risk to die in prostate cancer is 10 times higher than to die in skin cancer (malignant melanoma). The sun reduces the risk for several other types of cancer forms. Read more in our release. There you will find complete references. Cancer in the prostate is the most common cancer form in Sweden. According to The National Board of Health and Welfare 8 870 men were affected by the disease[1]. 2 473 died[2], i.e. 27%. To compare, 2 333 persons got malignant melanoma during the same period, 265 died, i.e. 11 %.
Tan – and halve the risk to increase prostate cancerIn the study scientists at three different cancer institutions compared 450 patients with severe prostate cancer and 455 men in corresponding ages and similar background, which did not have the disease. They found out that men who were exposed by to little sun had twice as much risk to develop prostate cancer as men who regular got exposed to a lot of sun[3].
In a study 1029 men who had developed prostate cancer where compared with 1371 healthy men corresponding ages and smoke habits. They discovered that men who had higher levels than the average of both 25-hydroxivitamin D and 1,25-dihydroxivitamin D had 45 % lower likely to develop prostate cancer[4].
Sun obstruct several other cancer types
Several independent studies show that different cancer forms obstruct by the D-vitamin you get when you tan. For example studies that shows that prostate cancer[5], breast cancer[6], lymph node cancer[7] and skin cancer[8] reduces because of the D-vitamin you get when you tan.
