Update Date: 2024-09-24 Source: Network

When observing moles on the skin, we sometimes may worry whether they are melanoma. Although it cannot be directly confirmed by visual inspection, the following suggestions can help distinguish between common moles and melanoma.

I. Appearance Characteristics:

Symmetry: Most common moles are symmetrical, whereas melanoma is often asymmetrical, with one half differing in shape and color from the other.
Border Clarity: The borders of common moles are typically smooth and well-defined, while the borders of melanoma may be irregular, blurred, raised, or indented.
Color Uniformity: Common moles are usually uniformly colored, while melanoma may have multiple colors within the mole, such as black, brown, blue, or red.

II. Size and Evolution:

Diameter: Generally, the diameter of a common mole is usually less than 6mm. If the mole's diameter is greater than 6mm, it's advisable to be vigilant about the possibility of melanoma.
Evolution: Pay attention to any changes in the mole. Common moles typically remain relatively stable over an extended period. If there are noticeable changes in the shape, color, size, or height of the mole, seek medical attention promptly for evaluation.

III. Symptoms and Sensations:

Itching or Pain: Common moles generally do not cause itching or pain, whereas melanoma may sometimes exhibit these symptoms.
Bleeding or Ulceration: Unusual bleeding, ulceration, or discharge can occur with melanoma, whereas common moles typically do not exhibit these signs.

While these characteristics can provide an initial assessment, a definitive diagnosis remains uncertain. If you are concerned about a mole, it's best to consult a dermatologist for professional evaluation. Only through careful examination by a physician and necessary tests (such as a biopsy) can a diagnosis of melanoma be made. Remember, early detection of melanoma is crucial, as early treatment improves the chances of cure. Therefore, regular self-skin checks and professional screenings are key to maintaining skin health.
