Premature development can bring serious psychological burden to children who are not yet mature and induce psychological diseases; 3. Some children’s precocious puberty is caused by a specific disease, such as tumors in the skull or ovarian tumors, testicular tumors, etc. If not diagnosed and treated in time, it can lead to more serious consequences and even life-threatening.
