Early diagnosis method of melanoma

Melanoma and common moles are easily confused, and doctors may even misdiagnose them. However, if you observe carefully, you can identify them by shape, color, and size. Once a mole expands or changes color, you should go to the hospital in time. The early diagnosis method of malignant melanoma is generally to look at the following four points. It is not difficult to distinguish between ordinary moles and malignant melanoma. Then let's take a look at the specific four points.

1. Asymmetry: Ordinary moles are generally symmetrical, while melanomas are generally asymmetrical.

2. Edges: Ordinary moles have clear edges and are clearly separated from the surrounding skin, while malignant melanomas have jagged edges. In addition, the surface roughness and scaly or flaky desquamation, sometimes exudation or bleeding

3. Color: Ordinary moles are usually black or brown, while melanoma can have a variety of colors. Among them, the most ominous is blue, indicating that the disease has developed to a more serious stage.

4. Diameter: Those smaller than 5mm are generally common moles, while those larger than 5mm are more likely to be melanomas.

In addition, it is important to note that when rubbing a mole, it is possible for the mole to become malignant. If the mole ulcerates, the stinging or burning pain will become more obvious, and even surrounding satellite lesions may appear, indicating that the disease has developed to an advanced stage. It should be emphasized that early malignant melanoma with poor structure requires pathological diagnosis in the hospital to accurately diagnose the disease.
