Dark skin people have less chances of developing skin cancer

Let’s study how dark people have less caches of skin cancer. For this we have to first understand the type of sun rays and there role in our body. There are mainly two types of damaging ultraviolet sunlight, UVA and UVB. UVA has an effect of ageing the skin and causing wrinkles and the damage to inner layers of the skin. UVB causes sun tanning but also burning. It can also cause other damaging to the skin. In some people, too much UVB may cause skin cancer.

Dark skinned people have greater amount and different form of melanin in their skin; moreover they also produce more melanin after times spend in sun light. Dark skinned people are much less sensitive than fair-skinned people. Melanin absorbs ultraviolet radiation, like a sun blocker. Therefore the cell beneath the melanin remains protected. However all people are at risk if exposed to too much of sun rays. People with fair skin, freckles, red or ginger hair are most risk. In general, darker the skin, lesser is the chances of developing the skin cancer.
