Little girl has a lump on one side of her breast

If a little girl has a lump on one side of her breast, it needs to be diagnosed based on her age. If the girl is over 12 to 13 years old, it may be normal breast development. If she is younger than 10 years old, it is necessary to consider that the abnormal growth hormone is caused by breast hyperplasia, breast cancer, precocious puberty, and endocrine disease. It is necessary to take the child to the hospital for a detailed examination, such as breast B-ultrasound, urinary system B-ultrasound, growth hormone and bone age tests, to find out the cause of the lump in one breast.

How to diagnose premature breast development in children and adolescents?

Pseudo-precocious puberty may be manifested as the level of sex hormones being consistent with age, but secondary sexual characteristics developing early, and the order of occurrence is the same as that of puberty. Specific manifestations include breast enlargement or premature pubic hair in men.

Simple chest enlargement due to hypertension: The female baby's chest is enlarged, which is usually unilateral and idiopathic. It may also remain unchanged or disappear later. Other sexual characteristics appear according to normal rules. It may be caused by the temporary metabolism of small amounts of estrogen by the uterus and ovaries. It should be distinguished from pathological precocious puberty and obesity-induced increase in chest fat.

Premature appearance of pubic hair in men with simple blood disorder: The reason is excessive metabolism of adrenaline and testosterone or the hair follicles are more sensitive to male hormones. It does not affect physical and mental health and is common in girls. His stature is taller than children of the same age, and should be distinguished from congenital adrenal hyperplasia and adrenal tumor.
