Why do people have moles, and what do moles on people s bodies mean?

Moles are formed when the mother is frightened (mostly in a dream) during pregnancy and puts her hands on her belly while resting.

This is during the embryonic stage, when the epidermis is not completely absorbed by the tissues.

A lot of moles, a lot of normal ones doesn't mean anything. If it is a film, or if the number is ridiculously large, then you have to go to the ** hospital to see.

There are broad and narrow senses of nevi, and the broad sense includes various congenital and acquired melanocytic nevi, sebaceous nevi, etc. In medicine, "nevi" is narrowly defined and is also known as nevus cell nevus, pigmented nevus, melanocytic nevus, or common acquired melanocytic nevi.

Congenital melanocytic nevi are not included. Nevus is the most common benign ** tumor in humans, which is the first manifestation caused by the increase of melanocytes in the epidermis and dermis. According to the location of the nevus cells within **, they can be divided into junctional nevi, mixed nevus, and intradermal nevi.

**It is thought that the occurrence of moles is related to genetic factors and environmental factors dominated by ultraviolet light.

Senile melasma: occurs in the exposed parts of the body of middle-aged and elderly people, such as the cheeks, neck, back of the hands and forearms, etc., mostly scattered in tan, small round, oval or irregularly shaped smooth or slightly higher than the skin surface of different sizes. Histological examination shows a normal increase in melanocytes without malignant transformation.

**Junctional nevi and mixed nevi that occur in the palmoplantar, waist, armpits, groin and other areas that are easy to rub should be considered for surgical excision in the following situations: Sudden increase in volume; dark or mottled in color; erosion, ulceration, bleeding, or swelling of the surface; Perceived pain or itching; Satellite lesions are present in the periphery. Laser** is also available.

I found that there have been more and more moles on my body recently, what is the reason?

1. What is the cause of moles on the body: Usually moles are mainly related to genetic factors, and may also be caused by acquired factors such as poor internal dust and secretion disorders, irregular diet and rest, and local infections, which cause the increase of melanocytes and functional disorders in the body, which in turn leads to the phenomenon of moles in patients.

2. Under normal circumstances, the long moles are benign and have almost no effect on physical health, so they can be left untreated.

3. However, if the appearance of the mole is asymmetrical, the pigment is uneven, the diameter is too large, the edge is irregular, the boundary is not clear, etc., it is necessary to consider the possibility of malignant transformation. At this time, Qingyu suggested that the patient should go to the ** department for local pathological biopsy as soon as possible, and conduct ** in time after the cause is clear.
