ABCD guideline

It has been suggested that this article or section be merged into Melanoma. (Discuss)

The ABCD guideline refers to a system of criteria for suspecting that a mole (skin marking) is potentially a cancerous melanoma. The initials stand for:

• Asymmetry - the mole is not round
• Border - the mole's border is not well-defined
• Color - the mole is dark or varied in color
• Diameter - the mole is greater than 6mm in size (around the size of a pencil eraser)

If any of the above conditions are present, a biopsy is recommended.
