Question
What’s causing the lump on one side of a 7-year-old girl’s breast?
Answer
For a seven-year-old, if one side of the breast has a lump, it is necessary to consider the child’s simple breast nodule. In this case, you should first check with a color Doppler ultrasound. Additionally, it is important to consider if the child has precocious puberty. It may be necessary to measure sex hormone levels, undergo an ovarian ultrasound, and have a pituitary MRI. If the child’s luteinizing hormone level exceeds 3.5-5.0, it should be considered as precocious puberty. The drug of choice for inhibiting gonadotropin activation should be Dafui.
