Although melanoma is one of the less common types of skin cancer, it is responsible for the majority (around 75 percent) of skin cancer related deaths. Part of the problem is that current diagnoses rely on subjective clues such as size, shape and coloring of a mole. With the aim of providing an objective measurement as to whether a lesion may be malignant, researchers at John Hopkins University have developed a prototype non-invasive infrared scanning system that works by looking for the tiny temperature difference between healthy tissue and a growing tumor.
