A nevus is a special kind of pigmented mole, most of which are autosomal dominantly inherited and have a certain chance of heredity. For some nevi caused by external factors such as ultraviolet radiation, they are generally not directly inherited to the next generation.
Nevus is a type of pigmented nevus, which is a benign tumor caused by a large number of nevus cells gathering in a certain area of the skin, usually appearing on the face, chest and other parts of the body, and occasionally accompanied by mild itching and other feelings.
If the parents carry the gene for nevus and most of the nevi are autosomal dominant, there is a certain chance that the offspring of these patients will develop the disease; if it is caused by long-term exposure to ultraviolet rays, it will not be directly inherited to the offspring.
When nevus appears, you need to consult a doctor in time, and if necessary, you can remove the nevus through surgery to prevent the nevus from becoming malignant and affecting the patient’s life.
