Regular monitoring of your skin can be the key to early detection of melanoma, the most dangerous form of skin cancer. Understanding the ABCDE rule is crucial for recognizing suspicious moles and spots that may require a dermatological evaluation.

What Is The ABCDE Rule?

A for Asymmetry

A mole that has one half unlike the other suggests possible melanoma. Symmetry in moles is typically a sign of benign growths, so any asymmetry should be checked.

B for Border

Uneven borders of a mole, characterized by edges that are jagged, notched, or blurred, are concerning signs. Normal moles usually have smoother, more even borders.

C for Color

A mole with multiple colors (shades of brown, black, tan, red, white, or blue) or uneven shades within the same mole might indicate a problem. Uniform coloration is typically less concerning.

D for Diameter

Moles should be monitored for their size. Those with a diameter larger than 6mm (the size of a pencil eraser) are more likely to be malignant, although some melanomas can be smaller.

E for Evolving

Any change in size, shape, color, or elevation of a mole, or the development of new symptoms such as bleeding, itching, or crusting, requires immediate attention from a dermatologist.

When Should You See a Dermatologist?

Regular Screenings

Individuals at higher risk for skin cancer—those with extensive sun exposure, numerous moles, or a family history of skin cancer—should undergo regular skin evaluations by a dermatologist.

Changes in Existing Moles

Any noticeable changes in an existing mole, as described by the ABCDE rule, should prompt a visit to a dermatologist.

New Skin Growths

Sudden or rapid development of new skin growths is another reason to see a dermatologist. These can include growths that are different from other existing moles in appearance, known as the “ugly duckling sign.”
