1 in every 10,000 people in the UK will develop a new case of malignant melanoma. Sun radiation is a contributing factor in 90 per cent of all cases of skin cancer. People of all ages can get skin cancer, but it is rarely seen in children. People who are exposed to large quantities of sun radiation can develop skin cancer as early as 20-30, but the disease is much more common in elderly people. Symptoms and treatment depend on what type of cancer it is.
Skin cancer is caused by exposure to sun rays particularly the ultraviolet rays.
The tumour, in particular, is greatly affected by exposure to sun radiation, and sunburn. A small number of cases are caused by hereditary conditions, but they are also triggered by exposure to sun rays. Solariums can also cause skin cancer. The colour of the tumours vary from brown or black to blue or orange. The tumours are characterised by having ragged edges and uneven colours.
