Gynecomastia is the enlargement or swelling of breast tissue in males due to an imbalance between the hormones estrogen and testosterone. It can affect one or both breasts, sometimes unevenly. Gynecomastia is common in newborns, adolescent boys during puberty, and older men, often linked to natural hormonal changes.
It is generally not a serious health issue, but it can cause discomfort or psychological stress.
A healthcare professional will conduct a physical examination and may order blood tests to check hormone levels. Imaging tests like mammograms or ultrasounds may be used to differentiate gynecomastia from other conditions, such as breast cancer.
Reducing risk factors like substance use, managing medications, and maintaining a healthy weight may help prevent gynecomastia. Regular medical check-ups can also aid in early detection and management.
