What causes skin cancer?
The vast majority of skin cancers are caused by exposure to ultraviolet light in the form of sun exposure but also from artificial sources such as solariums and arc welding. Other causes of skin cancer include exposure to cancer causing chemicals such as arsenic, or ionising radiation. These causes are much less common than ordinary sunburn from the sun. There are many types of skin cancers. Many Australians are burnt on a regular basis, and sunburns are often associated with outdoor activities we spend our leisure time doing, such as outdoor sports, gardening and swimming. Many outdoor workers are also burnt frequently although workplace health and safety prevention has helped to some degree.
