Quick answer. Gynaecomastia is enlarged male breast tissue and is very common — it affects many boys during puberty (often resolving on its own) and many adult men. Causes include normal hormonal changes, obesity (fatty ‘pseudo-gynaecomastia’), and certain medications, steroids or health conditions. Surgery is considered for persistent, true glandular tissue that does not settle and causes distress, using liposuction and/or gland excision. Recovery involves a compression garment and a few weeks of reduced activity. In Singapore it is a recognised surgical procedure (TOSP), so it may be MediSave- or insurance-claimable when medically indicated, unlike purely cosmetic surgery. See an SMC-accredited plastic surgeon and exclude medical causes first.
Gynaecomastia is the enlargement of breast tissue in men and boys. It is extremely common and usually benign: a large proportion of adolescent boys develop it during puberty, and it is also frequent in older men. Many cases improve or resolve on their own, especially those linked to puberty. When the enlargement persists, is firm and glandular, or causes significant self-consciousness, men may consider surgical reduction.
If you have male breast enlargement, you are not alone and it is rarely a sign of anything dangerous — but a proper medical assessment matters. A doctor should review your history and medications and, where appropriate, check for hormonal or other causes before any surgery is discussed. In Singapore, male breast reduction surgery should be carried out by an SMC-accredited plastic surgeon.

What gynaecomastia is, and why it is common
Gynaecomastia is firm, glandular breast tissue under the nipple, sometimes with extra fat. It is one of the most common chest concerns in men and is usually harmless. It commonly appears in newborns, again during puberty, and in older men, driven by shifts in the balance of oestrogen and testosterone. Pubertal gynaecomastia frequently settles on its own within months to a couple of years.
It is worth distinguishing true gynaecomastia (enlarged gland) from ‘pseudo-gynaecomastia’, which is mainly chest fat related to weight. The two can coexist, and they are treated differently — weight loss helps the fatty component but not a true gland.
What causes it
Common contributors include:
- Normal hormonal changes — in newborns, puberty and later life.
- Obesity / weight — increasing fatty chest tissue.
- Medications and substances — anabolic steroids, some anti-depressants, certain heart and prostate medications, some traditional or herbal remedies, and excess alcohol.
- Underlying medical conditions — less commonly, thyroid, liver, kidney or hormonal disorders, which a doctor should rule out.
Because some causes are reversible, the first step is a medical review — not surgery.
When is surgery indicated?
Surgery is usually considered only when gynaecomastia is persistent (typically present for many months and not improving), true glandular tissue that will not resolve with weight loss or stopping a culprit drug, and causing meaningful physical or psychological distress. Sudden, one-sided, painful or rapidly growing breast tissue, or a lump, should always be assessed medically to exclude rarer causes before any cosmetic discussion.
The surgery: liposuction and/or gland excision
Male breast reduction is tailored to what is causing the enlargement:
- Liposuction removes excess fatty tissue through small incisions and suits a mainly fatty chest.
- Surgical excision removes the firm breast gland, usually through a small incision around the lower edge of the areola.
- Combination — liposuction plus gland excision — is common, as most men have both.
It is usually a day or short-stay procedure. Where significant excess skin remains (e.g. after major weight loss), skin removal may also be needed, leaving longer scars.
Recovery, risks and results
Expect swelling, bruising, tightness and some discomfort. A compression garment is usually worn for several weeks to reduce swelling and support healing. Many men return to desk work within days and resume light activity within one to two weeks, avoiding strenuous exercise and heavy lifting for several weeks.
Risks include bleeding, haematoma, infection, fluid collection, altered or reduced nipple sensation, asymmetry, contour irregularities or a slight dip under the nipple, visible scarring, and the small possibility of recurrence (especially if an underlying cause — such as steroid use or weight gain — continues). Choose an accredited plastic surgeon and follow aftercare carefully.
Cost and MediSave in Singapore
Costs vary by surgeon and severity; as a rough market guide, surgery often starts from around SGD $4,000 and can be higher (commonly up to around $10,000+) for more extensive cases or combined techniques. Get an itemised quotation covering surgeon, anaesthetist and facility fees.
Unlike most purely cosmetic surgery, gynaecomastia reduction is a recognised surgical procedure in Singapore’s Table of Surgical Procedures, so it may be partly claimable via MediSave or insurance when it is medically indicated (for example, true glandular gynaecomastia rather than simple fatty enlargement). Eligibility and limits are decided case by case — confirm with your surgeon and insurer before proceeding.
