How possible is it that a cure will be found?

There is a chance that a cure will be found, but most likely not in the near future. Most treatment right now is aimed at just preventing skin cancer. Some experimental cures that are being worked on are repairing the UV damage after exposure by the injection of DNA repair enzymes into the skin. This had some success, but is still in the experimental stages. Also being developed is gene therapy, where they go in and place healthy genes where the defective genes are. This is very far away however, and still more in the theoretical stage than the developmental.
