I agree that cancer is a complicated disease but it is 95% environmental, and it is epigentical rather than genetic.
Unfortunately sunblock creams are carcinogenic.  As a fair-skinned human it is best to limit direct sun exposure, cover up with hats & shirts, and of course adopt a more saturated fatty animal based diet and avoid seed oils. 

 Sure! Best way it's to avoid direct sunlight exporsure the more the better. Totally agree. 

I was just pointing that he was probably using suncream but posting that sun it'd not bad for skin 🙃
