What's the matter with a hard lump under a boy's nipple?

A hard lump under a boy's nipple is caused by improper diet, or it may be caused by congenital pituitary gland disease. After a hard lump appears under the nipple, you need to go to the hospital for breast surgery for examination.

During the growth and development period of children, eating too many foods rich in phytoestrogens, such as soybeans, soy products and other foods, will increase the estrogen level in the body. Affected by the hormone levels, the breasts will develop mammary nuclei. At this time, you need to make adjustments to your diet, insist on doing aerobic exercise, and control your diet to reduce weight.

Boys are in the period of physical growth and development. They must maintain good living and dietary etiquette, try to have a diverse diet, and do not eat fast food or snacks.
