Melanoma is a less common type of skin cancer that can spread to other organs in the body.

The basic sign of melanoma is the appearance of a new mole or a change in an existing mole. This can occur anywhere on the body, but the back, legs, arms and face are most generally affected.

In many cases, melanomas have an uneven shape and more than one color. They may also be bigger than normal moles and can sometimes be itchy or bleed.

An "ABCDE checklist" has been created for people to tell the difference between a normal mole and a melanoma. 

The first five letters of the alphabet are a lead to help you recognize the notice signs of melanoma.

A is for Asymmetry. Most melanomas are asymmetrical. When a line is made through the lesion, the two halves don’t match and it goes off from a round to oval and symmetrical ordinary mole.

B is for Border. Melanoma borders are likely to be uneven and may have scalloped or notched edges, while common moles are likely to have smoother, more even borders.

C is for Color. Multiple colors are warning signs. While benign moles are normally a single shade of brown, a melanoma can have different shades of brown, tan or black. As it grows, the colors red, white or blue may also tend to appear.

D is for Diameter or Dark. While it’s best to detect a melanoma when it is small, it’s a warning signal if a lesion is the size of a pencil eraser (about 6 mm, or ¼ inch in diameter) or larger. Some experts say it is also essential to check for any lesion that is darker than the rest despite the size. Rare, amelanotic melanomas don’t have color.

E is for Evolving. Always check for changes in size, shape, color or elevation of a spot on your skin, or any new sign in it, such as bleeding, itching or crusting, as they may be warning sign of melanoma.

If you notice these warning signs, or something NEW, CHANGING or UNUSUAL on your skin see a dermatologist ASAP.
