Melanoma is the most dangerous type of skin cancer although it is not as common as other forms such as basal cell carcinoma and squamous cell but it is still the leading cause of death from skin disease. Because it is Melanoma Awareness it’s time to learn what it is, what it looks like and how to check for symptoms. The saying goes “knowledge is power” and that is certainly the case with melanoma!
SKIN COLOR AND THE ROLE OF MELANIN
Human skin has red, yellow, brown and blue tones. What we actually perceive in skin color is the reflected light off the skin. The best way to see true skin color is in natural light.
Melanin is also known as pigment. Melanin production is essentially a protective mechanism to prevent ultra violet damage to the cell nucleus.The basic unit of melanin is tyrosine, an amino acid which goes through a variety of conversions before melanin starts to form. Melanin is then transferred to the keratin cells by melanosomes. These cells rise to the stratum corneum, and eventually are sloughed from the skin.
