Malignant melanoma is the fifth most common cancer in the United Kingdom accounting for approximately 13,000 cases and more than 2,000 deaths a year. 1 The incidence of melanoma is rising steadily with a doubling of the number of cases every decade, a rate of increase that is more rapid than any other form of cancer. The median age of diagnosis is 57 years but increasing numbers of young people below the age of 40 are developing the disease. 1 There were 1589 new cases diagnosed in those below 40 years of age in the United Kingdom in 2010 with 110 deaths in this age group.
