What is a Gynecomastia?
Gynecomastia is the swelling of breast tissue in males. At times it may be painful or uncomfortable and affect one or both breasts. It can occur unevenly or in a portion of the breast and typically is not a serious problem.
What causes Gynecomastia? 
Gynecomastia is caused by an imbalance of the male hormone testosterone and the female hormone estrogen. One in four men experiences gynecomastia to some degree and it is most prevalent between the ages of 50-70.
Diagnostic testing and examinations
Your doctor will ask questions about your medical and drug history as well as health conditions that run in your family. A physical examination will be done as well as possible blood and medical imaging exams.
Treatment for Gynecomastia
Gynecomastia may simply resolve without treatment or your doctor will discuss treatment options with you based on your individual situation.
Notify your doctor if you are experiencing a change in the size, a lump, discharge from the nipple area or pain and discomfort in your breast tissue.
