Early Signs of Melanoma
Melanoma vs Normal Mole: Key Differences
Learn how normal moles often behave, which melanoma warning signs matter, and why change over time is the safest comparison.
What a normal mole often looks like
The American Cancer Society describes many normal moles as evenly colored brown, tan, or black spots that are flat or raised, round or oval, and generally smaller than 6 millimeters. It also notes that almost all moles are harmless. [1]
The most useful word is often stable. A mole that has looked the same for many years is less concerning than a spot that is new, evolving, symptomatic, or very different from your other spots.
What melanoma warning signs look like
The ABCDE rule focuses on asymmetry, border, color, diameter, and evolving. It is a memory aid, not a diagnosis. [2]
Some melanomas do not fit the classic checklist. The American Cancer Society emphasizes that new spots, changing spots, and the "ugly duckling" sign are important reasons to seek medical review. [1]
Why photos help
A single photo can be misleading because lighting, angle, focus, and skin tension change how a mole appears. A consistent photo timeline is more useful because it lets you compare the same spot over time.
Dermela is designed for that comparison. It helps you organize the visual timeline and the symptoms you noticed, so a clinician gets a clearer history.
Track the next change clearly
Dermela keeps mole photos, notes, and symptoms organized in a timeline you can bring to a clinician.
