A recent study of skin cells, in the journal Science, demonstrated that UV-exposed skin cells harbor a multiplicity of genetic mutations that can develop into cancer.
By sequencing the genes in skins cells obtained at the time of plastic surgery on the eyelids (to remove drooping skin), the researchers were able to demonstrate multiple genetic defects in skin cells, many of which occur within the genes that are associated with skin cancer. This ‘bulbling cauldron’ of genetic variants ultimately give rise to skin cancer, and the UV light is the driver of those mutations.
How does the skin stay effective and cancer free with all of this genetic variations? It’s difficult to say, but the fact that your skin is undergoing massive genetic changes all the time is an amazing proof that things are not quite as calm as they may appear on the outside, when it comes to your skin and sun exposure.
