What is Moles

Moles are small-pigmented tumors, consisting of clusters of nevus cells containing melanin, a pigment of the skin. Moles vary in color; some being yellow or brown and others are purple and black. They may be large or small, flat or raised, smooth, hairy, and some even have the appearance of warts. A few moles may be present at birth and are known as birthmarks. Occasionally a mole may become malignant, a condition known as melanoma, a particular dangerous form of skin cancer.

Ordinary moles are usually benign and the chance of their developing into malignant tumors is very less. But a special kind of mole called a junction nevus may appear like any other mole, and yet it can become highly malignant. Any mole that is growing rapidly and turning a darker color may be malignant and should be removed.

Generally malignant melanomas are more likely to develop in the legs. Moles that are constantly subjected to irritation as from belts or tight bands are always more likely to undergo malignant change. Such moles should be removed. As a rule, if there is hair growing out of the mole, it is not likely to be malignant.

People who have fair skin have greater effect of the sun on the skin. These individuals are more sensitive to sunburn as well as changes in moles, so it is very necessary for the use of protective sunscreen lotions. Moles may be pigmented or non-pigmented. If pigmented, color may vary from light tan to black. A mole that is blackish in color, and especially if elevated and rough in appearance, may be a melanoma
