Question
A seven-year-old nine-month-old girl, 128 centimeters tall, and weighing 27.1 kilograms. In September of this year, the parents noticed that her breasts had slightly increased in size, with small hard lumps felt upon palpation, but without any tenderness. Apart from this, no other abnormalities were found.
Answer
According to your description, the child’s growth and development indicators are normal. At seven years and nine months, the average height is 123.5 centimeters, and the average weight is 23.5 kilograms. The skeletal age usually differs from the actual age by about one year. The breast condition you mentioned falls within the normal range. However, to rule out the possibility of precocious puberty, it is recommended to undergo a six-item sex hormone test, pituitary magnetic resonance imaging, bone age test, and reproductive organ color Doppler ultrasound examination for further diagnosis and the formulation of appropriate treatment plans.
