You don't need much sun to get it and Vitamin D can be obtained from other sources. Even if you never get cancer, the sun damages and ages your skin. Most people don't realize their skin has taken damage unless they get a painful sunburn, but any amount of tan is the result of some degree of sun damage. Of course, a lot of sun at once resulting in a burn, increases the risk of cancer. That's particularly true if it happens in youth when your skin is still growing. That's one of the highest risk factors for skin cancer- repeated sunburn in your youth. Some people have more melanin in their skin naturally and the damage is slower, but it's true to a varying extent for everyone. Fair-skinned people are particularly vulnerable to it. People always comment about how I look young for my age. I avoid sun exposure and when I absolutely must be in it, I take a shower in sunscreen.
