This part of a man is most susceptible to cancer when it is damp

Do you know what it means when the surface of a mole is moist or has scabs formed? Pigmented nevus is a benign tumor belonging to the melanin system and is composed of nevus cells. Simply put, the skin is divided into the epidermis and dermis from the surface to the deep layer. When nevus cells are located at the junction of the lower epidermis and dermis, it is called a junctional nevus; when nevus cells are located in the dermis, it is called an intradermal nevus; when nevus cells are located in both the epidermis and the upper dermis, it is called a mixed nevus. When a pigmented nevus turns into cancer, there may be the following early signs.

Beware of ten types of pigmented moles that are prone to cancer

1. Pigmented nevi generally appear between birth and 30 years old. The appearance of new pigmented nevi after the age of 30 should be regarded as suspicious.

2. People whose pigmented nevi are repeatedly infected.

3. When the pigmented nevus has a tendency to bleed.

4. Sudden and persistent itching of the pigmented mole.

5. There is an inflammatory red halo around the pigmented nevus, or satellite nevus appear around it.

6. The original hair on the pigmented nevus suddenly falls off.

7. The surface of the pigmented nevus is moist or has scabs formed.

8. When pigmented nevus is subjected to long-term and repeated friction or traumatic stimulation, there are potential factors for canceration.

9. When a nodule, ulcer or bleeding appears in the center of the pigmented nevus.

10. The darkening of a pigmented mole is not an absolute indication of malignant transformation, because all pigmented moles can turn black during sexual maturity and pregnancy. However, if any single mole becomes darker than other moles or becomes unevenly dark in a short period of time, or if it grows rapidly, it is an early sign of cancer.
