• 一种symmetry
• B.order
• Color
• D.iameter
• E.volving

一种symmetry

两侧的对称的痣看起来非常相似。如果你穿过痣的中间（从任何方向）绘制一条线，双方的边缘将非常吻合。

In an asymmetrical mole, the two sides won’t match in size or shape.Cancer cellstend to grow more quickly and more irregularly than noncancerous cells.

B.order

正常摩尔的边缘将具有清晰，明确的形状。鼹鼠与周围的皮肤分开。

如果边界似乎模糊 - 就像有人在线之外彩色 - 它可能是痣是癌症的标志。

Color

D.iameter

• redness
• 缩放
• bleeding
• oozing
