Patient's question:
Male, 23 years old, had always been very overweight. Previously, having large breasts didn't bother him much. However, after losing weight, he discovered a hard lump under his nipple. But when pressed, it didn't hurt and could move. The area under the nipple was very soft and pointed.Doctor's answer:
Breast hyperplasia is generally divided into two major categories: primary and secondary. Primary cases are more common in adolescent boys and elderly men, primarily caused by transient elevation of endogenous estrogen or a decrease in androgen levels, and often resolve on their own. Secondary cases are commonly associated with liver diseases, testicular diseases, adrenal gland disorders, thyroid diseases, diabetes, or tumors in the urinary-genital or nervous systems. Long-term use of estrogen in prostate diseases, or prolonged medication use for other conditions, can also lead to it. For your situation, it is recommended to identify the underlying cause and receive symptomatic treatment.
