Question
Recently, a girl has been observed to have a hard lump in her chest, with one side larger than the other, and it feels painful when touched. Three months ago, she went through the postpartum period.
Answer
For this situation, it is recommended to first undergo a breast ultrasound examination, as well as gynecological ultrasound examination and testing of intracellular sex hormone levels to assess the possibility of precocious puberty. Once diagnosed, a corresponding treatment plan will be formulated. The normal development age for girls is 9 to 11 years old. If secondary characteristics such as breast development appear before the age of 8, the possibility of precocious puberty should be considered. It is advised to take the child to the hospital for relevant examinations and professional analysis.
