This year over 50, 000 people will be diagnosed with melanoma, the most dangerous form of skin cancer. When diagnosed early, melanoma can be cured. However, melanoma is much more likely than the other types of skin cancer to metastasize, or spread, to other parts of the body. That is why it is so important to inspect your skin on a regular basis, in addition to a complete annual skin exam by your physician, and to report any suspicious changes as soon as you notice them.

How can I tell the difference between a melanoma and an ordinary mole?
Most people have multiple moles on their bodies. A mole can be present at birth or it can appear later in life. Sometimes, several moles appear at about the same time, especially on sun- exposed skin. Once a mole has developed, it usually stays the same size, shape and color for many years. A quick and easy way to examine your moles is by using your ABCDEs!

A= Asymmetry
Test your mole for asymmetry by drawing an imaginary line down the middle: do the two halves match? Ordinary moles are usually round and symmetrical, while most early melanomas are asymmetrical.

B= Border
Ordinary moles are round or oval and have well- defined, smooth, even borders. Melanomas often have ragged, uneven, or notched borders. Also, spreading of pigment from the border of the mole into surrounding skin is a warning sign of melanoma.

C= Color
Ordinary moles are usually one color throughout and are usually brown, tan or flesh- colored. Melanomas may have several colors (black, brown, red, white, blue) or an irregular pattern of colors.

D= Diameter
Moles can be many different sizes, but ordinary moles are generally less than 1/4 inch (6 millimeters) in diameter, which is the diameter of a pencil eraser. Melanomas may be as small as 1/8 inch, but are often larger.

E= Enlargement
Ordinary moles usually do not change over time. A mole that suddenly grows in size or rapidly becomes elevated is suspicious for melanoma.
