Breast Concerns in Boys: Care Instructions

Overview

Hormones sometimes cause breast growth in male children. This is called gynecomastia. Using some medicines also can cause breast growth. It can also be caused by a medical condition.

In babies, this usually goes away in a few weeks to a year after birth. In preteen and teenage boys, this often goes away within 6 months but may last up to 2 years. Many boys get this breast growth from rapid hormone changes during puberty.

Talk with your doctor if your teen is concerned about breast size or shape or is worried by these changes.

How can you care for your child at home?

• If your child's breasts are tender, he can put a cold washcloth or ice pack on them for 10 to 20 minutes at a time. Put a thin cloth between the ice and the skin.
• Tell your doctor about all medicines your child takes. Some medicines can cause breast growth in boys.
• Advise your son to wear loose-fitting shirts. This will make the breast growth easier to hide. Also, a loose shirt will not rub the breasts as much as a tight shirt.
