Pseudogynecomastia is an enlargement of the breasts that occurs when a child is about 8 years old and manifests itself as simple early breast development. Symptoms include enlargement of one or both breasts, which may be painful to touch, and a breast diameter of less than 5 centimeters, but the nipple and areola are normal, and there is no other development of secondary sexual characteristics. Pseudo-breast development may be caused by the intake of estrogen from outside, resulting in hormone level disorders in the body, which can be alleviated through dietary regulation and exercise. If breast development occurs, you need to go to the hospital in time, under the guidance of a professional doctor to carry out reasonable treatment, through various examinations to determine whether it is pseudo-breast development.
