Question
A girl, 8 years and 11 months old, has experienced pain in her right breast for about 3 to 4 days, with a small hard lump palpable. The left breast is normal. She is 135 cm tall and weighs approximately 27 kilograms.
Answer
Considering the child’s size and current situation, it is necessary to examine her. You can consider checking sexual hormones, ultrasound, bone age, and other aspects. There is a wide age difference in breast development for girls, but most occur between the ages of 8 to 13. The above situation should be a normal physiological phenomenon and there is no need to worry. In terms of symptoms, it is necessary to rule out precocious puberty. An examination is needed.
