Gynecomastia is enlargement of male breast tissue, often related to hormones, medicines, or systemic illness.
The main symptom is swelling or fullness under one or both nipples. It may feel tender, uncomfortable, or embarrassing, but is often not dangerous.
Imaging helps when doctors need to confirm that the swelling fits gynecomastia rather than another type of lump, or when the pattern looks unusual.
Ultrasound or mammography can help confirm the pattern and exclude a suspicious mass when needed.
Management focuses on the cause and may involve medication review, endocrine evaluation, reassurance, or surgery in selected cases.
This entry explains the condition. The next step is having a radiologist interpret your specific scan, not a general definition.
