What Cause Skin Cancer?

The skin is made up of two main layers, the epidermis and the dermis. The epidermis is a thin layer which acts as a barrier to prevent moisture from leaving the body and fluid and chemical from entering the body. The epidermis is several skin cells , thick and develop from the deeper epidermis, gradually maturing, migrating towards the surface, becoming a keratin protein, factory and finally flaking off at the surface.

Most of cells in the epidermis are skin cells called keratinocytes where the function is making keratin as the structural protein of the skin. There are other cells in the epidermis and these includes melanocytes. These make the pigment which gives the skin it's color and become more active when expose to the sun. When there is a sun damage, there are excess pigmentation on different areas of the skin. Melanocytes are the cells which are linked to melanoma- a serious skin cancer and it's solar radiation which is most responsible for the development if this type of cancer.
