What are the diagnostic methods for melanoma

Melanoma is a tumor disease that is extremely harmful to people. Its characteristics are high malignancy and early metastasis. If the disease is not diagnosed and treated in time, the patient may be in danger of death. Therefore, once there are signs of the disease, go to the hospital for examination as soon as possible. So, what are the diagnostic methods for melanoma? Let's take a look.

1. Is the rash raised? The early symptoms of melanoma are that the rash is not raised at first, but then slightly raised and gradually forms nodules. Or there is erosion, scab, pus, water, especially blood on the surface. This is one of the ways to judge melanoma.

2. The early symptoms of melanoma are unclear borders around the rash, or one side is clear and the other side is blurry, giving people a vague feeling.

3. The rash is asymmetrical. According to experts, the first rash is relatively stable on one side, and the way to judge melanoma is that the other side expands to the periphery and becomes irregular and rough on the epidermis, which is also an early symptom of melanoma.

4. The method of judging melanoma is whether the rash pigment deepens or decreases. It can be light brown, dark brown, black, dark red, purple, gray-green, blue, or even disappearance of pigment, which is the early symptom of melanoma.

5. The rash grows rapidly in a short period of time. It doubles in size within 1 to 2 months. The diameter of the congenital nevus rash is greater than 6 mm. The method of judging melanoma is especially for those occurring on the palms and soles. If the diameter of the nevus exceeds 15 mm, it indicates the possibility of malignancy.
