Tucked into the sunbaked rolling hills of Brazil's midwest, Araras is home to what is thought to be the largest single group of people suffering from a rare inherited skin disease known as xeroderma pigmentosum, or "XP."

Those with the disease are extremely sensitive to ultraviolet rays from sunlight and highly susceptible to skin cancers. It robs victims of the ability to repair the damage caused by the sun.
