A 45-year-old man attends as he is concerned about his ‘moles’. His father was diagnosed with a malignant melanoma at the age of 49. He has worked in construction since leaving school and has spent many years working outside. He tells you that he has spent about 10 years working in North Africa, the majority of the time he spent outside in the sun.

The patient has fair hair and blue eyes. You examine his skin and he has about 60 common naevi 2 mm or less in diameter. He also has four atypical naevi (naevi with flat and raised areas, oval in shape, with some colour variation) which are all 6 mm or more in diameter. He reports no changes in any of the moles but as he has so many is worried about his risk of skin cancer.

What is the greatest risk factor for this patient to develop a melanoma?
