A common mole is a form of growth on the surface of the skin. It occurs when the skin pigment cells or melanocytes grow in clusters. Moles are common in most adults and occur in places and areas, which are most exposed to the sun. Moles may be present from birth or may appear at a later stage. Moles develop until the age of forty.
Moles are generally round or oval in shape and their surface is smooth with distinct edges. They are dome shaped. Common moles are pink, tan or brown in color. People with dark skin complexion develop dark-colored moles.
Sometimes, moles may change in color and shape. This might be an indication of a skin cancer condition known as Melanoma.

When moles change in color and size, it is because of Melanoma. Several tests have to be carried out to detect whether a mole is cancerous or not, and after that, medical measures must be taken. Melanoma is a serious form of skin cancer and should be attended to immediately.
