Gynecomastia
Gynecomastia is enlargement of male breast tissue, often related to hormones, medicines, or systemic illness.
When to get help quickly: Prompt review is important if the lump is hard, fixed, one-sided, associated with nipple discharge or skin change, or if it is growing quickly.
Common symptoms
The main symptom is swelling or fullness under one or both nipples. It may feel tender, uncomfortable, or embarrassing, but is often not dangerous.
When imaging helps
Imaging helps when doctors need to confirm that the swelling fits gynecomastia rather than another type of lump, or when the pattern looks unusual.
What radiology does
Ultrasound or mammography can help confirm the pattern and exclude a suspicious mass when needed.
What usually happens next
Management focuses on the cause and may involve medication review, endocrine evaluation, reassurance, or surgery in selected cases.
