Is malignant melanoma as harmless as a mole?

People often mistake malignant melanoma for moles. Moles are harmless to people, so is malignant melanoma also harmless? Today, we have asked an expert to tell us in detail about malignant melanoma .

Malignant melanoma is a highly malignant tumor that develops rapidly, is prone to local and distant metastasis, and is not very sensitive to radiotherapy and chemotherapy. However, moles do not have these characteristics and will not threaten human life and health if they do not worsen.

The "ABCD" principle of distinguishing moles from malignant melanoma:

The so-called "ABCD" stands for four symbols, namely the first letters of the English words asymmetry, edge, color, and diameter.

Asymmetry: The two halves of an ordinary mole are symmetrical, while the two halves of a malignant melanoma are asymmetrical.

Border: The border of an ordinary mole is smooth and clearly demarcated from the surrounding skin, while the border of a malignant melanoma is irregular and serrated. In addition, the surface is rough with scaly or flaky desquamation, sometimes with exudate or bleeding, and the lesion is higher than the skin.

Color: Ordinary moles are usually brown, brown or black, while malignant melanomas are brown or tan with pink, white or blue-black. Blue is the most ominous color, while white indicates that the tumor will regenerate spontaneously. Nodular malignant melanomas are always blue-black or gray.

Diameter: The diameter of an ordinary mole is generally less than 5 mm, while the diameter of a malignant melanoma is larger than 5 mm.
