Why do some people get skin cancer yet others dont?

Answer 1

Light skinned people, especially blue-eyed people or people with freckles are far more likely to get skin cancer than people with plenty of natural pigment in their skin. We (light skinned people) should not go into the sun without LOTS of sun-blocker. Dermatologists will all tell you that sun exposure is accumulative. We can only get so much sunlight in our lives, then we will get skin cancer.

Answer 2

Your risk of obtaining skin cancer depends on your total exposure to UV rays. IE A person that goes to a traditional tanning bed has a significantly higher chance of getting skin cancer. When in the sun (even in the winter) they recommend that you wear some form of sunscreen. For women sunscreen of some strength is already in most daily moisturizers. You can buy moisturizing creams for men with sunscreen in them as well. Your risk can also be affected by the strength of the UV rays; i.e. when I was living on the equator my risk of getting skin cancer increased because I was closer to the sun (I also sunburned a LOT faster!)
