ABCs of Identifying Skin Cancer

Summer is here and with it comes longer days and more intense sunlight. This increases exposure to UV rays which can lead to skin cancer. Today, we’ll discuss two ways to evaluate moles for potential signs of melanoma. They are the ABCD method and the EFG method.

ABCD stands for:

• A – Asymmetry: The two sides of the mole look different from each other

• B – Border: Look to see if the order is irregular and not smooth

• C – Color: Most normal moles have one set color, not multiple

• D – Diameter: Melanomas are usually bigger than a pencil eraser (6mm)

ABCD is good for catching most melanomas. However, nodular melanoma does not follow these patterns. For this type of cancer, use the EFG method.

EFG stands for:

• Elevated – It’s not flat to the skin

• Firm – It’s not squishy like most moles

• Growing – It is noticeably growing bigger

Most nodular melanomas adhere to the patters described in the EFG method. However, if you are concerned about any strange or unusual skin growth, contact a dermatologist. They will be able to examine and determine if it is benign.
