4.1 INTRODUCTION Invasive and in situ malignant melanoma together comprise one of the most rapidly increasing cancers in the world. Invasive melanoma alone has an estimated incidence of 73,870 and an estimated total of 9940 deaths in the United States in 2015 [1]. Early diagnosis is particularly important since melanoma can be cured with a simple excision if detected early.
