What is the cause of the hard lump on the boy's chest?

During the development of boys, parents should pay comprehensive attention to them, so that they can know whether there are any abnormalities in the boys' physical development. If there are any, they should improve them in time to avoid causing various problems. So what's the matter with boys having lumps in their chests? Many people don't understand this. The following is a detailed introduction so that parents can have more understanding of such problems and know how to deal with them.

What is the cause of the hard lump in the boy's chest?

Breast development is generally the first sexual change that occurs in girls during puberty. This is mainly due to the high level of estrogen secreted by the female ovaries, which stimulates the development of mammary alveoli and mammary ducts, causing the breasts to bulge. However, some boys who have reached puberty may occasionally feel a little pain in their breasts. When they touch them carefully, they find lumps in their breasts, which makes them feel anxious.

In fact, 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, their testicles secrete a small amount of estrogen while producing androgens, but the amount is extremely small. 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.

Some boys do not care about subtle changes in their bodies and may not even notice these changes in their breasts. 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. So, neither the boys nor the parents need to feel embarrassed.

After understanding what is going on with boys' chest lumps, parents do not need to worry too much if the area of ​​the lumps is not very large. In addition, boys are very likely to develop chest lumps when they are growing, so the lumps will slowly disappear as boys continue to grow. Parents should just let nature take its course and not choose medications for boys, otherwise it will affect the child's body.
