12 causes of Cancer | Sunlight exposure

12 cause of Cancer : Sunlight exposure.

• The Ultra Violet or UV rays are responsible for most of the cases of Melanoma or skin cancer, especially in the western countries.
• Every person living on earth is more or less always exposed to sunlight. So why are only the people in the west mostly found to have skin cancers?
• There are 2 main reasons for this :

• The effect of sunlight exposure on the people is such that, it doesn't lead to more melanin production (like in dark skinned people), but it slowly alters the genetic constitution of the cells, and leads to mutations. A series of which results into skin cancer. 
• Increasing use of 'Tanning bed' which mainly emit UVA rays, which are responsible for causing Melanoma.

So, these are the 2 main causes of skin cancer which are again, preventable. And can be prevented by simple protective measures like covering the skin and use of a good sunscreen. Also, avoiding the use of 'Tanning beds' reduces the risk.
