Pigmented nevus may be cancerous

summary

Pigmented nevus is a benign new organism composed of nevus cells. This disease is common and can occur in almost everyone. It can occur from infancy to old age. With the increase of age, the number of pigmented nevus often increases significantly in puberty. Women tend to have more moles than men. This disease belongs to developmental malformation. During the movement of melanocytes from neural crest to epidermis, due to accidental abnormality, melanocytes are formed by local aggregation. Many women who love beauty, pay attention to their own image, choose to point out the nevus, but now it is said that random point nevus may induce cancer. Let's take a look at the following.

Pigmented nevus may be cancerous

First: the pigmented nevus is composed of pigmented cells, most of which are benign nevus. Generally speaking, they will not be affected. However, the pigmented nevus lesions that people are worried about are not groundless, because most people can't distinguish the pigmented nevus and skin malignant tumor. If they are misdiagnosed, random points of nevus will lead to the occurrence of canceration, which should be paid special attention to. Some pigmented nevus do have a certain relationship with the occurrence of melanoma, may promote the production of some tumors, so we need to pay attention to pigmented nevus.

Second: for the long in palms and plantars, waist circumference, armpit, groin, shoulder and other easy to friction parts of the nevus should be closely observed, especially some irregular edge, uneven color, to pay close attention to, once found rapid expansion or part of the high or burst, bleeding should be promptly removed. Treatment should be thorough to avoid secondary recurrence.

Third: many people can't tell whether a black nevus is a melanoma, so they randomly point the nevus. Now the so-called "point the nevus" methods are nothing more than laser, freezing and other methods. In fact, these methods are very dangerous operations for real melanoma. Because the early stage of melanoma is still in the epidermis and does not enter the dermis, this kind of operation is likely to turn the early stage of melanoma into the middle stage, that is, if the melanoma is brought into the dermis, subsequent metastasis may occur.

matters needing attention

If it's not melanoma, and it's really a "mole", it can be "dot". We can find the change of nevus and the appearance of abnormal nevus early by self-examination. Such as the original nevus in a year increased significantly, color significantly deepened, shiny; When the edge of nevus becomes irregular or satellite like small nevus appears, or several nevus fuse, and the surface is uneven, don't be careless. Be sure to see an experienced specialist in time for standardized biopsy, so as to eliminate the possibility of malignant transformation of nevus. Personal experience of spot mole
