I agree about your environmnet being a big factor. But I have to wonder what the skin cancer rate is in the sunny Meditteranian.
Following WWII, my gruncle lived in Africa as his skin grafts wouldn't take in the British climate. He was like a patchwork quilt of grafts following his plane being shot down. Most white expats in Africa got nose cancer from the sun eventually. He moved back eventually, but had stayed out of the sun and never got nose cancer.
