A European multicenter case-control study found no significant association between outdoor work and melanoma risk.

◐Partially SupportedReducing vegetable oil and oxidized polyunsaturated fats in the diet is associated with improved diet quality and potentially reduced sun sensitivity.

◐Partially SupportedLipids in skin cell membranes susceptible to sun oxidation increase the likelihood of burning and DNA damage.

◐Partially SupportedWorking outdoors more is associated with a higher incidence of squamous and basal cell carcinoma.

✕Not SupportedThe mainstream dermatological view that sun exposure causes skin cancer is illogical given potential benefits of sunlight that cannot be replicated by supplements.
