12-year-old boy has a lump in his breast

It is actually normal for a 12-year-old boy to have breast lumps, because the age of 12 is a developmental stage, and the boy's sex hormones are constantly increasing. At this time, the breasts and breast tissues are very sensitive to the secretion of female hormones. This is breast swelling and pain caused by hormone disorders in the body. It will disappear on its own in the later stages of development, so there is no need to worry too much.

It is normal for a 12-year-old boy to have a lump in his breast. This phenomenon occurs when the breasts and breast tissue are very sensitive to estrogen and the body's sex hormone levels are disturbed.

Rehabilitation guidance: It will often disappear on its own in the later stages of development and no treatment is needed. In addition to the above-mentioned physiological hyperplasia, there is occasionally pathological hyperplasia, such as a concomitant symptom of liver disease, testicular dysfunction, adrenal disease, thyroid disease, tumors, etc. Therefore, if you suspect any of these possibilities, you should seek medical attention as soon as possible to avoid delaying the treatment.

Breast lumps during male puberty are normal physiological changes. The breasts are mainly composed of mammary tissue, fat and connective tissue. There are special structures on the surface of mammary cells that can recognize and accept estrogen. When estrogen binds to the receptors of breast cells, the metabolism of breast cells becomes active, causing breast cells to proliferate and the breasts to develop and bulge. After male adolescents enter puberty, the testicles secrete a small amount of estrogen while producing androgen. Of course, the content is negligible. Estrogen causes breast cells in the nipple area to proliferate continuously, leading to the formation of lumps in the breast. Breast lumps in adolescent boys are often limited to the area below the nipples and may sometimes be painful when touched. According to a survey, among male adolescents aged 13-15, 1/3-2/3 were found to have unilateral or bilateral nipple protrusion, an increase in the diameter of the areola, and pigmentation, but less than 1/5 had breast nodules. Since the increase in estrogen levels in male adolescents during puberty is only temporary, this type of breast lump usually disappears on its own after a few months to a year.

It is recommended to observe for a period of time. If the breasts are still enlarging, go for examination to find out the cause and treat it. If it is just a problem of puberty, it will return to normal after a period of time.

It is recommended to relax and keep a good attitude. Live a happy life. If you are really worried, you can get checked to determine the condition first and then decide how to treat it.
