At what age do girls start to develop breasts

As girls get older, do they start to wonder when their breasts will start to develop? We girls shouldn't feel embarrassed about this, because this is something every girl will have questions about, and breast development is also part of a girl's physical growth and development. So, at what age do girls begin to develop breasts? Let’s find out together. Because it means their daughters are growing up.

Breast development begins between the ages of 8 and 12. Initially, the mammary glands that make up the breasts and the surrounding protective fat tissue form a button-like bulge in the breasts and the surrounding areola (breast bud stage). After that, the nipples begin to grow larger, the areola gradually expands, and the color of the breasts and areola gradually deepens. Around the age of 14 to 15, breast development becomes more obvious and the breasts become noticeably raised. At the age of 16 or 17, the breasts are full, with clear lines, slightly sunken areola, and large and prominent nipples. At around the age of 18 or 20, the size and shape of the breasts are that of an adult woman (breast stage). However, the girl's breasts cannot secrete milk at this time, and it will take until she gives birth.

Breast development in girls marks the beginning of the development of female secondary sexual characteristics and is also a signal of the onset of puberty. Under the action of sex hormones, the breasts of girls aged 9 to 11 begin to develop. First, the nipples protrude and feel like a small lump, with some swelling and pain. Later, the breasts gradually swell and the light brown areola around the nipples gradually deepens in color and increases in size. Later, the nipples become large and protruding, and the breasts become fuller. Due to the influence of many factors such as genetics, environment, nutrition, and physique, the age at which girls enter puberty varies greatly from person to person. Generally speaking, breast enlargement from the age of 8 to 14 is normal. If breasts have not developed after the age of 16, you should go to the hospital to check the cause.

Precocious puberty refers to the onset of sexual maturity at a significantly earlier age. Medically, it refers to the premature development of children's gonads, that is, the testicles of males and the ovaries of females, which causes the early development of reproductive organs and the appearance of secondary sexual characteristics. The medical definition is that sexual development begins before the age of 8 for girls or before the age of 10 for boys. Early development of the reproductive system (including the appearance of adult secondary sexual characteristics), often occurring in a sequence similar to that of normal puberty. Precocious puberty is accompanied by accelerated physical development and growth, resulting in increased height and muscle development, premature closure of the epiphyses, and earlier growth cessation.
