Question
A 9-year-old girl has developed lumps on both sides of her breasts. Does this mean she has precocious puberty? How should treatment be approached?
Answer
For girls, the development of secondary sexual characteristics before the age of eight is defined as precocious puberty. However, for a 9-year-old girl, breast development may be a normal sign of entering adolescence. Lumps on both sides of the breasts are likely due to breast development during puberty. If parents still have concerns, it is recommended to consult a local gynecologist for examination and, if necessary, to undergo tests for sex hormones and bone age.
