Question
My daughter is 6 and a half years old. A few days ago, I noticed a hard lump beneath her left nipple, which is oblong when standing and the size of a bean when lying down. It is tender to the touch, and her right side is normal. She currently weighs 25 kilograms and is 130 centimeters tall. What should I do?
Answer
This is a normal physiological change and has nothing to do with precocious puberty. Girls typically start menstruating between the ages of 11 to 18. But before that, as they grow daily, the secretion of sexual maturation hormones can cause some rapid and significant changes, not daily maturation. Therefore, a 6-year-old child may develop some hard lumps, which will then gradually mature. This is normal, and there is no need to worry.
