People choose to have this procedure to remove excess tissue and fat from their breasts. Gynecomastia surgery can improve your self-image and confidence. Many people decide to have this procedure to enhance the way they look, either in clothing or when they aren’t wearing a shirt.

This procedure includes liposuction, surgery or both. Your provider will recommend the technique that’s right for you.

What happens before gynecomastia surgery?

Before surgery, your provider will discuss your options, goals and medical history. Your provider may recommend a complete blood count (CBC) or other tests to evaluate your health and determine what’s causing gynecomastia.

They will examine you, measure your breast tissue and screen you for male breast cancer. They may also take photographs of your breasts.

You may need to stop taking certain medications, such as blood thinners, prior to surgery. If you smoke, ask your provider about quitting smoking before your procedure. Tobacco use can slow the healing process. The day before surgery, your provider will tell you when to stop eating and drinking. You should wear loose-fitting clothing when you arrive at the surgical center or hospital.
