what age do breasts stop growing

Breast development begins between the ages of 8 and 13, and breasts typically continue to grow as the girl’s body fat increases during puberty. They become rounder and fuller, and it’s common for one breast to develop faster than the other. Over time, they should even out, but many adult women find their breasts differ slightly in size, which is normal. Breast development can continue until the age of 18, and at this point, the breasts have typically reached their final size, which is ultimately determined by a woman’s genetics and weight. However, breast tissue may undergo further changes due to hormones, such as from pregnancy and menopause. Breast growth typically continues throughout puberty, and most girls will have reached their adult height and breast size by the age of 17.
