Question
A parent is concerned about a hard lump inside the nipple of their six-and-a-half-year-old daughter and has taken her to a local hospital for examination. The parent wants to know if this situation is related to precocious puberty and how to further confirm the diagnosis.
Answer
According to the examination results, the girl’s breast development falls within the normal range. Some children may experience breast development earlier, and the condition of the left breast may be related to excessive daily contact. Generally, the average weight and height for children of this age are 22 kilograms and 120 centimeters, respectively, which can only be used as a reference for good physical condition and is not an exact indicator of precocious puberty. If there is a suspicion of precocious puberty, hormone level tests should be conducted to confirm the diagnosis.
