Australia has one of the highest rates of skin cancer in the world, with over 95% caused by sun exposure. The document outlines steps to be sun smart like wearing protective clothing and sunscreen. It describes the three main types of skin cancer - melanoma, the most dangerous, and basal cell carcinoma and squamous cell carcinoma. Skin cancer may appear as crusty sores or changing moles.
