Then he casts a critical eye over melanoma and its relationship with sunlight. He makes the point that melanoma most commonly occurs in places that are less sun exposed. He also alludes to the fact that melanoma is more common in indoor workers than outdoor workers. He doesn’t mention this, but I think it’s also worth bearing in mind that most melanomas do not occur in typically sun-exposed parts of the body. Dr Spence does point out, though, that there is scant evidence that sun protection reduces the risk of melanoma, and none at all that it saves lives.
therefore: Sunscreen is more marketing bullshit.
