Skin cancer. Abstract illustration of skin cancer caused by sunlight,showing a setting sun over a "landscape" of human skin in section. Cancer cells (blue) are spreading through the epidermis (red) and dermis (yellow). Skin cancer is most common in the elderly,pale-skinned,and people who live in hot sunny climates. In Australia over half the population has had skin cancer by age 75. The condition shown here is malignant melanoma,a type of skin cancer caused by tumours of pigment prod- ucing cells in the epidermis. Malignant melanomas usually start in moles,and are caused by mutations induced by ultra-violet radiation in sunlight. They can be fatal if not treated early | |
