What is the difference between normal skin, a freckle, a mole, and melanoma?
In: Biology
normal skin is just… skin. Not sure what you want me to say about that. A freckle is a cluster of normal skin cells where the cells just have more pigment than the surrounding skin. A mole is a skin lesion that contains higher than usual concentrations of pigment and the pigment cells themselves are different than normal skin pigment cells. Moles can be congenital (existing at birth or acquired. They are usually harmless. Melanoma is a cancer of the pigment-containing cells in the skin.
