Why does a person with red hair and light complexion have a higher risk of getting skin cancer?
People with light complexions have less skin pigmentation. Skin pigmentation absorbs ultraviolet radiation and protects your DNA from damage from the sun. If you have less pigmentation and less protection for your DNA you are more likely to get skin cancer. This is why it is recommended that you should wear sunscreen.
Why the people have dark skin and is melanin contributed to dark skin?
Melanin is the pigment which helps our skin to be defensive against over exposure. Normally when you are exposed to sun light the skin will produce melanin automatically. But people from cold climates won't need melanin as the sun light is not strong over there. So people from colder area tend to be white. But people from hotter climates need melanin to prevent sun burn so their body is programmed to do so. More melanin means the darker the skin. The reason why melanin turns our skin to black is, black color can absorb the light, but white will reflect the light. If the light is being reflected only the skin will be exposed to heat and that will damage the skin which is sunburn. But dark skin will absorb the heat and transfer the heat to the inner body parts under the skin and thus by having less damage on the skin.
Is light reflects on human body?
yes some light rays do reflect from human skin but they are so less that they are almost ignorable. human skin's got pores and so majority of the light rays enter through them. hence human skin does not reflect back light as shiny sufaces like mirror etc. do (That is the reason why other people are almost invisible to you.)

Why do people with darker skin have less chance of getting skin cancer?
because darker skin contains higher levels of melanin(sp?) think of that as an interrior (or sub dermal)suntan lotion. I THINK I think it is more of a man caring for the skin such as lights, which means using sun protection because dark skin contains higher levels of melanin than others. Yes, because of melanin in dark skin, people with this skin coloring are less likely to get skin cancer than people with light skin. The pigmentation in dark skin is the key factor to not receiving compared to someone with light skin. It's all about the how the skin cells multiply. Now, that doesn't mean people with dark skin still can't get skin cancer. THEY CAN wherever there's light skin on them such as the skin underneath your fingernails, palms, and bottoms of their feet.
