What is the Real Relationship between Sun Exposure, Skin Cancer, and Vitamin D? Published on May 19, 2024 FacebookTwitterRedditLinkedInEmail   Several studies conclude that regular, sensible, non-burning sun exposure throughout the lifetime, and higher vitamin D levels, are related to decreased incidence of melanoma and increased melanoma survival rates Key Points Two important distinctions about the relationship between sunshine exposure and skin cancer should be made: 1) intermittent, or sudden, drastic exposure to high intensity sunlight (resulting in sunburn) does increase the risk of skin cancer, and 2) regular, moderate, non-burning exposure to sunshine (sensible sunshine exposure) has been associated with lower risk of skin cancer Moderate, non-burning sunshine exposure initiates specific repair mechanisms within skin cells, including DNA repair enzymes and the production of local vitamin D, which work to prevent damage accumulation; vitamin D synthesized in the skin has several anti-cancer properties, including roles in cell differentiation, cell death, cell adhesion, and oxidative stress, all of which can help protect against the development of cancer Several studies are reviewed to demonstrate how increased, sensible sunshine exposure and increased vitamin D levels are related to decreased melanoma incidence and mortality, decreased tumor size, and improved response to melanoma treatment The sun has gotten a bad reputation because of the association between ultraviolet (UV) exposure and skin cancers.…

Many Types of Cancer Reduced with Higher Amounts of Lifetime UVB and Sunshine Exposure JCTA NOTE: this is not medical advice and is only for your information and should not be promoted by a salon.  Published on May 15, 2024 FacebookTwitterRedditLinkedInEmail   Research over the last few decades have confirmed a significant relationship between increased lifetime sunshine and UVB exposure and a decreased risk of many different types of cancer Key Points Studies describing the relationship between UVB exposure, sunlight, and vitamin D on the incidence of colon, breast, ovarian, and other cancers have been published by the Garland brothers and other authors, with a recurring theme of decreased cancer risk with increased UVB and vitamin D; a study by Munoz and Grant found a significant association between increased solar radiation and and a decreased incidence of 23 different types of cancer A significant dose-response correlation between UV exposure and breast cancer risk was found in one study, such that women in the highest exposure groups had a 30% lower risk of breast cancer compared to women in the lowest exposure groups; overall, this study saw a negative correlation between UV exposure and breast cancer risk, especially among women over 40 years of age, and women who did not tan or who covered their arms and legs while in the sun also had a higher risk of breast cancer A detailed analysis of studies on sun exposure and melanoma and found that continuous, regular sun exposure was not associated with melanoma, but rather, sunburn doubled the risk of developing melanoma and intermittent, high-intensity sun exposure proposed a 61% increased risk for melanoma Cancer is the second leading cause of death in the United States, second only to death from heart disease.…
