It can be hard to differentiate between breast tissue and fat because they are similar in appearance. The biggest difference between the two is that breast tissue does not go away with a change in diet and regular exercise, often requiring surgical procedures to be removed. An easy way to tell the difference between excess breast tissue or excess fat in the chest is to check for an actual hard lump behind the nipple. Call us today to book an appointment with our gynecomastia treatment specialist, or visit one of our New Jersey locations: in North Brunswick, Princeton, and Surf City.
