Question
Last night, when my second-grade daughter came home, I noticed her breasts had suddenly grown significantly, about 6cm in size. My daughter didn’t seem to mind, but I was extremely worried. What could be the cause?
Answer
Precocious puberty refers to the early onset of sexual development, with breast development being one of the signs. However, this requires an ultrasound to determine whether it is due to glandular growth or fat accumulation. It is crucial to clarify this. If it is glandular growth, it may indicate precocious puberty, and a professional pediatric hospital’s endocrinology department should be consulted for an ultrasound of the uterus and ovaries in adults to examine the development of follicles and determine the actual situation regarding precocious puberty.
