The main signs of malignant transformation of pigmented nevus

In clinical medicine, pigmented nevus are called benign tumors. They can exist anywhere on our skin and generally do not cause any harm to our body. However, they will gradually grow larger with age. First, if they are in a more obvious place, they will directly affect a person's appearance. Second, due to environmental or external factors, pigmented nevus may become malignant, which will cause harm to the body. The following editor will briefly introduce the main signs of malignant transformation of pigmented nevus.

Everyone has pigmented moles of varying sizes, some on the face, some on the back. In daily life, we often ignore pigmented moles. In fact, if pigmented moles are not handled properly, they will cause big trouble. Moles on the palms, soles of feet, and neck require special attention, as moles in these areas are often rubbed and are more likely to worsen.

In fact, pigmented nevus is a benign neoplasm composed of nevus cells. Almost everyone has moles, from infants to the elderly. The number of moles increases with age and increases significantly during adolescence. Women generally have more moles than men, and white people have more moles than black people. There are many types of manifestations, most of which are dark brown or ink-black in color, and a few are colorless moles. The formation of moles is a developmental malformation. During the migration of melanocytes from the neural crest to the epidermis, accidental abnormalities occur, resulting in the local aggregation of melanocytes. Moles generally do not require treatment other than cosmetic reasons. If treatment is needed, it must be that the mole has worsened due to various reasons.

So, why do moles get worse? First, if pigmented moles are constantly infected or damaged by external factors, they are easily stimulated and then get worse. Secondly, the sudden darkening of a mole is also a sign of the mole's worsening. However, this is not an absolute sign of deterioration, as moles may become darker or larger as women mature or become pregnant. Of course, if a pigmented mole suddenly becomes darker and larger than other moles, then it needs to be taken seriously. Third, if the pigmented mole suddenly increases in size and has symptoms of redness, swelling, bleeding, itching and pain, you should seek medical attention immediately. In addition, if the mole is not completely treated with laser, electrocautery, etc., it may become cancerous due to irritation.

In our daily life, we should be careful not to rub the moles frequently, let alone scratch or pick them. There are a lot of bacteria in the fingernails, which may worsen the infection of the moles if we are not careful. Moreover, recently many people who love beauty have gone to some small shops with no guarantee to remove moles for the sake of beauty. This method of mole removal is absolutely not allowed. For everyone's health, it is better to go to a regular hospital to remove moles.
