It is generally believed that the development of breasts before the age of eight in girls, and the onset of menstruation before the age of ten; in boys, the development of testicles before the age of nine, appearance of secondary sexual characteristics, and accompanied by rapid physical development, are referred to as precocious puberty. Early development refers to the situation where, before puberty, not only the sexual organs but also other organs in boys and girls begin to develop simultaneously.

Therefore, precocious puberty and early development not only differ in the age of onset but also focus more on whether the sexual organs are developing in coordination with the body's other organs. The differences lie not only in the timing but primarily in whether the development of the sexual organs is coordinated with the development of the body's other organs. If the sexual organs and the body's other organs are not developing in coordination, it indicates precocious puberty. If they are coordinated, and merely occurring earlier than usual in puberty, it is considered early development.

What should I do if I find out my child is maturing early?

Interventional treatment for precocious puberty varies according to different causes. In principle, once diagnosed with central precocious puberty, aggressive pharmacological treatment is recommended, using inhibitory hormones to suppress development to pre-pubertal levels and inhibit further development of the ovaries and uterus. For peripheral precocious puberty or pseudoprecocious puberty, the cause must be removed. Clinically, if a child accidentally ingests their mother's contraceptive pills causing transient vaginal bleeding, it is essential to carefully inquire about the medical history, thoroughly understand the cause, and determine the treatment method. Also, ask if there has been any special dietary intake recently, including foods or drinks high in estrogen, and if so, remove the cause for treatment.

Where is precocious puberty manifested?

Precocious puberty is primarily characterized by the development of breasts in girls before the age of 8, which leads to a diagnosis of precocious puberty. In boys, an increase in testicular volume and thickening of the penis before the age of 9 or 9.5 years also constitutes a diagnosis of precocious puberty. Once children show signs of precocious puberty, it is crucial to promptly take them to a hospital for the following relevant examinations to determine whether the condition is affecting the child's physical and psychological health. 1. An examination of bone age to determine if it impacts the child's height; 2. An ultrasound of the gonads to verify the severity of sexual development; 3. Under the detailed examination of a doctor, observe whether it affects the child's psychology, thereby providing further reasonable treatment based on the actual manifestations of the child.

Premature breast pain has now stopped hurting, does that mean it's healed?

When girls develop breasts before the age of eight, they may experience pain at the breast bud nodules. Pain does not necessarily mean recovery; it is possible that as the breast bud enlarges, the pain will naturally disappear. Whether treatment is needed once precocious puberty occurs and whether it has reached a level of cure mainly depends on the assessment through pediatric bone age, gonadal ultrasound examinations, or a combination of brain pituitary MRI and blood hormone levels to analyze the severity of the condition. For mild cases, with appropriate medication, diet, and exercise guidance, children can reach a basic level of clinical cure. Severe cases require the control of the child's sexual development through the injection of gonadal hormones or hormone-releasing analogues. Psychological impacts due to early sexual development may also necessitate behavioral and psychological interventions.

Does precocious puberty require growth hormone treatment?

For children with precocious puberty, a small number require combined treatment with growth hormones. For instance, if a child's height growth rate is less than 4cm, it is necessary to add growth hormones to promote growth and development. The second scenario involves using a bone age test; if the height is less than 151cm, growth hormones can also be used in combination for treatment. In the third scenario, if the child's bone age at the time of consultation has already exceeded 11.5 years, has significantly increased, or even if menstruation has started and their height has been clearly affected, it is generally advised to use growth hormones in combination with treatment.

Does a hard lump in a child's breast mean precocious puberty?

Children's breasts have lumps, and it is indeed necessary to consider whether it is precocious puberty, but there are other conditions that can cause lumps in children's breasts. For example, cysts or other solid occupying lesions. Besides the development of secondary sexual characteristics, including the development of breasts, growth of axillary hair, and even menstruation in girls, if these secondary sexual characteristics appear before the age of nine and are accompanied by a recent rapid growth in height, then we need to consider the possibility of precocious puberty.
