Little boy has a small lump in his breast

Some mothers accidentally find that their children have a small lump in their breasts, and the nipples are slightly bulging. If the child is between 8 and 13 years old, excluding some breast disease factors, it is usually a manifestation of the body's just beginning to grow and develop. Don't worry, just remind the child to protect his breasts well. If some children are very young, it may be a manifestation of precocious puberty.

What causes precocious puberty in children? 1. What is precocious puberty in children? Precocious puberty is an abnormality of sexual development characterized by the early onset of estrus. Precocious puberty refers to the appearance of secondary sexual characteristics before the age of sexual development, i.e., breast development, the appearance of pubic hair and armpit hair in men, rapid growth in height and weight, and development of external genitalia. At present, it is generally believed that if a girl's secondary sexual characteristics grow and develop before the age of 8 or her menarche before the age of 10, and a boy's sexual development just begins before the age of 10, it can be diagnosed as precocious puberty.

What causes precocious puberty in children?

1. Precocious puberty of the central nervous system

It is also called pathological precocious puberty. Because the hypothalamus-pituitary-gonadal axis starts to function too early and GnRH is metabolized by a single pulse, the patient has growth and development of the uterus, ovaries or male testicles in addition to the growth and development of secondary sexual characteristics.

2. Refractory precocious puberty

Also known as physical precocious puberty, it is caused by the reduced sensitivity of the hypothalamus-pituitary gland to the negative feedback of estrogen, which causes the release of gonadotropin and premature metabolism of growth hormone. It is more common in women, accounting for more than 80% of girls' CPP, while it is only about 40% in boys.

3. Secondary precocious puberty

Common central nervous system errors include: hematoma or space-occupying tumors: hypothalamic pituitary hamartoma, cystic tumor, granuloma; central nervous system infection; secondary damage: traumatic, post-operative radiotherapy, chemotherapy or radiotherapy; negative regeneration, growth and development abnormalities: hydrocephalus, septum opticus dysplasia, etc.

4. Other symptoms

Primary hypothyroidism.

5. Jugular precocious puberty

It is also called pseudo-precocious puberty. It is precocious puberty caused by the effects of sex hormones on the hypothalamus-pituitary gland and the pituitary gland. There is growth and development of secondary sexual characteristics and an increase in estrogen levels, but the hypothalamus-pituitary gland-gonad axis is immature and there is no growth and development of sex hormones.

6. Some people have precocious puberty

Simple premature breast development, simple premature development of male pubic hair, simple premature first menstruation.
