Being an 11 year old boy with enlarged breasts can be very difficult when trying to fit in at school & society. Most boys during puberty will have some increase in breast volume that will resolve over time. Unfortunately, for some boys the volume persists. This usually consists of breast tissue but can also be adipose (fatty tissue). The medical term for this problem is Gynecomastia. It is more common in overweight boys and men. Gynecomastia can be caused by hormone imbalance, tumors, marijuana and certain medicines. All of the problems need to be ruled out by physical exams and lab studies. I usually tell the families of young boys and teenagers to wait a few years to see if the problem resolves. If they are overweight, I recommend they lose weight near their ideal body weight. If the Gynecomastia persists or is causing psychology problems, then this can be treated by surgery. If the breast volume is caused by adipose (fatty tissue) and is minimal to moderate volume, this can easily be corrected with liposuction with 2 very small barely visible scars. If the breast volume is the result of breast tissue, then the tissue needs to be excised. This can be done through a small incision around the areola (dark skin around the nipple) if not extremely large breast or droopy. If the breasts are more droopy or large, skin needs to be removed. This can be done around the areola (peri-areola) if minimal to moderate problem. This usually leaves a barely visible scar around the areola. If very large breast or droopiness, more skin will need to be removed. The most common technique removes skin horizontally across the chest leaving a horizontal scar across the chest. This leaves a more visible scar. Because I do not like this type of scar, if possible, I would combine the peri-areolar and skin excision along the lateral chest wall where the scar is more hidden under the arm area. It is important that you see a REAL board certified plastic surgeon by the American board of Plastic Surgery. These are the only REAL plastic surgeons fully trained to take care of gynecomastia.
