Early breast development

Introduction Through drug testing and animal testing, some hormone-like substances are found in some tonics. Long-term use not only can make the breast develop early, but even produce the role of promoting gonadal development. Children with pseudo-precocious puberty often have breast enlargement and early breast development when they take nutritional supplements for 2 to 3 months. They may be progressive or fluctuating, but if they are found to stop taking them in time, they can usually recover in about half a year.

Cause

First, nutrition improves. The current family living conditions have become superior, nutrition has improved, diseases have decreased, and children's growth and development have accelerated, leading to an increase in sexual development and sexual maturity.

Second, environmental pollution. At present, the industrial pollution of the society is increasing, and the food also contains a large amount of pesticide pollution or hormonal pollution. These pollution residues are a cause of precocious puberty in children after being passed through the skin or directly consumed.

Third, hormone-containing foods. Many of the vegetables and poultry now contain a lot of hormones. Some sex hormones can cause precocious puberty when they enter the human body indirectly.

Fourth, blindly tonic. Tupple is one of the culprit causing precocious puberty in children. Some parents often give their children an appetite, brain and brain health supplements. As everyone knows, these supplements often contain hormones, which can cause long-term use in childrens blood. Hormonal levels rise, leading to precocious puberty in children.

Fifth, contraceptives and cosmetics lead to precocious puberty.

Sixth, sexual information. The current society is a highly developed information society. Not only can children get a lot of sexually suggestive pictures from TV, but they can also access sexual information from the Internet. "There is still access to yellow information at any time in the network. There are also some adult VCDs. If children have more contact, they will stimulate children's psychology too early and eventually make them precocious." Some parents, often in front of their children, said that they are ordering dolls. Parents who marry a child to a topic, do not know, these words will have an unexpected effect on children's sexual sprouting and sexual consciousness, and may even lead to precocious puberty. This has been similarly expressed by many experts in Shanghai, where the precocious puberty study is relatively mature.

Pseudoprecocious puberty can be expressed as the size of the gonads is consistent with age, but the second sexual characteristics develops in advance, and the order of occurrence is the same as the order of puberty. Mainly manifested as breast enlargement or pubic hair, the following types are available:

1 simple breast development: baby breast enlargement, mostly unilateral, progressive, can also be static or regressed later, other sexual signs appear according to normal rules. May be caused by a temporary secretion of a small amount of estrogen. Should be identified with true precocious puberty and obesity caused by increased chest fat.

2 simple pubic hair early: the reason is excessive secretion of adrenal androgen or hair follicles sensitive to androgen, does not affect health, more common in girls. Its body is higher than the same age, it should be differentiated from congenital adrenal hyperplasia and adrenal tumors.

3 male female breasts: the breasts of newborns can be increased by the hormones from the mother, and disappear after a few weeks. 2/3 adolescent boys have breast enlargement, which is caused by an increase in testosterone and a slight increase in estradiol, which disappears after a few months. Some male and female breasts are familial and have nothing to do with endocrine. The disease is also seen in testicular stromal tumors, adrenal feminine tumors, primary testicular hypoplasia (Kleinfelt's syndrome), male pseudohermaphroditism.

4 drug-induced sexual precocity: the use or misuse of estrogen can cause boy, girl breast development, areola pigmentation, exogenous estrogen can cause beard, pubic hair, mane growth. After the drug was stopped, the symptoms subsided for half a year.

5 congenital adrenal hyperplasia: 21-hydroxylase deficiency, progesterone and 17-hydroxyprogesterone accumulation, increased testosterone synthesis. Can cause male or female pseudo-precocious puberty.

Differential diagnosis

Big breasts: also known as breast hypertrophy, large breasts or giant breasts, refers to excessive breast development of women, containing hyperplasia of glandular and fat connective tissue, volume is abnormal, and the body is obviously out of tune. Chest compression can occur, chronic mastitis, pain, heavy shoulder pain and skin erosion under the breast. Big breast disease is more common in adolescent girls or young women, often on both sides, occasionally limited to one side. The main symptoms of breast disease are: neck and shoulder and chest heavy feeling and pain, mainly due to the lowering of the center of gravity of the huge breast. Brachial plexus compression, eczema or inflammation under the breast folds, and even ulceration. In addition, what is more important is the psychological disorder caused by breast cancer. It has been reported that huge breasts can be turned over and back to the shoulders, drooping down to the navel.

Central precocious puberty: 50% of children with central precocious puberty begin to develop earlier than 6 years old. Women have breast development, enlarged labia minora, estrogen-dependent changes in vaginal mucosal cells, enlarged uterus and ovaries, and pubic hair. Menarche. Males showed increased testicles and penis, pubic hair, muscles, and thicker sounds. Both men and women have accelerated growth and accelerated bone formation, which can eventually lead to a lifetime high below the target height. In the case of central nervous system diseases such as intracranial tumors, there may be headache, vomiting, vision changes or other neurological symptoms and signs.
