Melanomas

Photo: Man with melanomas
Each adhesive dot on former Banbury, Australia, lifeguard Don Bennewith represents a removed melanoma. Melanomas are malignant tumors that begin as pigmented moles and are caused by excessive sun exposure. Due to their generally fair skin and Australia's high levels of UV radiation, Aussies have some of the highest rates of skin cancer in the world.
