Holistic Health Show with Carl Helvie logoA new study published in Nature concluded that sunscreens do not protect totally against the development of skin cancer. Using genetically modified mice susceptible to melanoma the researchers disproved that ultraviolet light causes mutations in the DNA of melenocytes in a gene called p53. P53 is one of the genes considered a guardian  of the genome that is  key in detecting and repairing damage accumulating in cells from ul;ultraviolet light  and is a major barrier for the body against cancer. They found that sunscreen protects against immediate radiation damage including sunburn, but the radiation can penetrate and damage the DNA cells and as a result cause cancer.
