Breast hypoplasia in girls

We all know that, under normal circumstances, after a girl reaches puberty at the age of 12, her body will undergo certain changes, such as menstruation and slight swelling of the breasts. However, some girls develop slowly or their development is not normal. What is the cause of breast hypoplasia in girls?

What is the cause of breast hypoplasia in girls? Breast hypoplasia is mostly caused by congenital diseases, and a few are caused by acquired factors such as breast binding during adolescence, chest burn scar contracture, etc. It is mainly caused by the lack of glandular tissue, while the skin remains intact and elastic (except for burns). Unilateral disease is often accompanied by hypoplastic or absent pectoralis major muscles. Bilateral disease may be caused by the insensitivity of breast tissue to sex hormones during its mature stage. Nipple development may be normal.

The breast is an ectodermal organ that originates from the skin and belongs to the superficial structure of the chest wall. Girls' breasts begin to develop at the age of 12 to 13 and are basically mature at the age of 15 to 17. Although there are differences among different races and ethnic groups, the mammary gland is generally composed of 15 to 20 lobes. Breast hypoplasia is a congenital disease, mainly characterized by a lack of glandular tissue, while the skin remains smooth and elastic.

1. Insufficient secretion of female sex hormones

Insufficient secretion of female sex hormones directly affects the growth and development of mammary ducts and the branching of the mammary gland terminals, which can lead to poor development of small mammary lobes and alveoli, thereby affecting breast development.

2. Pubertal developmental disorders

Malnutrition during adolescence caused by various reasons affects and hinders the normal development of breasts.

3. Endocrine disorders during puberty

Lack of sexual knowledge and sense of shame among adolescent girls can lead to psychological disorders, causing endocrine disorders and affecting normal breast development.

4. Breast Binding

Binding the chest due to psychological barriers or wearing a bra that is too tight can easily cause breast hypoplasia.

5. Lack of physical exercise

Due to long-term lack of moderate physical exercise, the chest muscles are underdeveloped.

6. Genetic factors

Now we understand that breast hypoplasia in girls is caused by many factors. Therefore, when parents of girls realize that their daughters have these adverse developmental conditions, they should take their daughters to the hospital for formal diagnosis and treatment as soon as possible. This way, early detection and treatment can be achieved, and the children will not miss the best development period.
