Breasts just beginning to develop

Before puberty, there is no difference in the appearance of boys' and girls' breasts. Starting from the age of 7 or 8, various systems of a girl's body begin to grow and develop. About two years later, under the interaction of ovarian hormones, pituitary hormones, and insulin, the breasts begin to grow. The age of breast development also varies from person to person, with the average being 10.8 to 11.4 years old. If the breasts have not developed after the age of 16, you should be alert to whether it is sexual development retardation or incomplete development of the uterus and ovaries.

Girls' breast development usually begins when their nipples begin to grow, around the age of 9 to 10. It starts with breast hyperplasia, which produces a breast nodule. It feels like a lump or a small lump, which is painful when pressed. From 12 to 13 years old, the mammary glands and fat gradually increase, the breasts gradually become prominent and elastic, and the nipples and nipples become darker in color. The fully developed breasts are hemispherical and located between the 3rd to 6th ribs.

When girls reach the age of 16 to 18, the growth and development of the chest gallery and breasts are almost complete. Use a soft tape measure to accurately measure from the upper bottom of the breast through the nipple to the lower bottom of the breast. When the distance between the left and right sides exceeds 16 cm, you should wear a bra. There are many types of bras on the market at this stage. You can choose according to your body shape, weight, season and breast development. It is better to choose pure cotton products that are soft, breathable and absorbent. The length of the bra camisole should be appropriate and wider (not narrower than 2cm-3cm).

The ideal bra should be able to support the breasts during physical activities, limit the movement of the breasts as much as possible without affecting breathing, and leave no marks of compression on the skin after taking it off. The size of the bra should be moderate. If it is too small, it will compress the breasts and nipples, affecting breathing, the growth and development of the diaphragm and breasts. If the bra is too large, it will not be able to support and protect the breasts. The bra should be taken off when sleeping at night to avoid affecting breathing and blood circulation.
