What is Gynecomastia?
Gynecomastia is the growth of glandular breast tissue in men. It occurs as a noticeable lump behind the nipples, sometimes quite large, and it is often accompanied by a significant accumulation of localised fat that enlarges the breast. In some men, it can occur on just on one side of the chest. In the vast majority of cases, gynecomastia is not an issue of physical health. However, for many men, it can act adversely on their psychological well-being.
Although quite rare in men (less than one in a thousand), a lump behind the nipple can be due to breast cancer, and regardless of any decision about treatment for gynecomastia, it is sensible to undergo a diagnosis with an ultrasound scan.
