This exposure triggers genetic defects that cause skin cells to multiply rapidly and form malignant tumors. People who are genetically predisposed to the disease at are even higher risk. Nearly six decades ago, preserved mummies from Peru dating back 2,400 years were examined and found to have signs of melanoma on their skin and cancerous growths that spread from there to their bones.
