Horizon: Horizon reports on a handful of children around the world cannot tolerate the sun. Any exposure leads rapidly to skin cancer. They must either play indoors during daylight or be protected from head to toe in UV-proof suits. These children suffer from a strange and rare genetically-inherited disease, Xeroderma Pigmentosum, or XP, which means that within seconds of the sun's rays touching their skin, they are in danger of developing skin cancer.
