Men can also develop breast fibroadenomas, usually due to increased levels of estrogen in the body. Gynecomastia is a kind of hard knot caused by the overgrowth of fibroblasts and overproduction of extracellular matrix due to the increase of estrogen level in the body. It can be slightly hard to touch, and the area can gradually expand, usually the size of green beans or soy beans, and part of it can also grow to one or two centimeters in diameter. The tumor body often has no obvious changes and hyperplasia is not obvious. Gynecomastia fibroma is usually small in diameter, only tiny particles exist in male breasts, and will not cause any impact on personal life. You can take some drugs such as testosterone to regulate the balance of hormones in the body, so as to achieve the purpose of inhibiting the growth of breast fibroids. However, if there is a relatively large or the possibility of malignant changes, surgical excision treatment is needed. If the symptoms of gynecomastia fibroma appear, you need to go to the hospital in time for clear diagnosis and standardized treatment.
