Believe it or not, a single external organ of the human body plays a vital role in our lives. “The skin is the largest organ of the human body; [like personality], it varies from individual to individual”, as stated in National Geographic (science.nationalgeographic.com). The skin, according to Sandra Lawton a clinical expert in dermatology, is comprised of three layers. “The outside layer of skin is known as the epidermis, the layer that can be seen. The epidermis consists of hairs and sweat pores. The deeper layer of the skin is known as the dermis, which is separated from the epidermis by a dermal-epidermal junction and consists of sweat glands, oil glands, blood vessels and hair follicles. The last layer is the fatty layer which increases with weight gain but provides the body with insulation “(Lawton, 2013). If the skin is not protected, it can develop cancerous growths as a result of excessive exposure to ultra-violet (UV) radiation, causing skin cancer. Though skin differs in color due to melanin, protective sun pigmentation, some people have variations of discolored patches on their skin. Where does skin discoloration come from? Some people have light patches; others have hairy patches, while some may not have them at all. These variations of patches on the skin are common skin abnormalities such as birthmarks, liver spots, and freckles. What happens when abnormalities of the external organ affects the functions of the internal organs? This paper discusses several skin pigmentations that can be associated with the development of cancer due to several factors: the type of pigmentation, and the genotype associated with skin pigmentations and genetics in relation to cancer.

exposed the relationship between skin color and spatial arrangement (Jablonski and Chaplin 2002). Individuals with darker skin are found closer to the equator compared to lighter skinned populations (Jablonski and Chaplin 2002). It was originally thought that having darker skin was associated with an evolutionary defense mechanism concerning the protection from skin cancer (Jablonski and Chaplin 2002). However, further investigations suggest that skin pigmentation is dependent upon natural selection
have little to no melanin, which causes a loss of pigment in hair, skin, eyes, and a decrease in vision. There are different forms of albinism, but the two most popular are called Oculocutaneous Albinism and Ocular Albinism. Oculocutaneous Albinism has a pigment deficiency in skin, hair, and eye color, along with decreased vision in the eyes. Ocular Albinism has a defect in the eyes affecting vision, but there is no difference in skin and hair color (4). Donating money towards the genetic research of

Researching the World of Plastic Surgery In the creation of our beings, we are blessed, and sometimes cursed with features we, as freethinkers, might not otherwise have chosen for ourselves. Certain circumstances however, may arise on the journey known as life, forcing us to reconstruct these features in an effort to construct normal, healthy, lives. Often, we are compelled to reconstruct these features in an effort to enhance an otherwise normal, healthy life. For the individual unaware of the
