UV light may be a greater risk for melanoma than suspected
Studies conducted in yeast show that exposure to ultraviolet light (UV) induces new types of DNA damage that may cause the deadliest form of skin cancer, malignant melanoma. While melanoma has been associated with UV light, this study directly links UV exposure to the atypical mutations known to spread the disease. The results also indicate that UV light can induce a more diverse spectrum of mutations than previously suspected. (2020-11-17)
