NHS Choices offers this melanoma advice “The most common sign of melanoma is the appearance of a new mole or a change in an existing mole. This can happen anywhere on the body, but the back, legs, arms and face are most commonly affected. In most cases, melanomas have an irregular shape and more than one colour. They may also be larger than normal moles and can sometimes be itchy or bleed. An "ABCDE checklist" has been developed for people to tell the difference between a normal mole and a melanoma.
