Enlargement of true breast tissue in men, not simply fat. It is common, it is usually harmless, and for most men the difficulty it causes is social rather than medical, which does not make it any less worth treating.
Gynecomastia is growth of genuine glandular breast tissue in a man, driven by the balance between testosterone and oestrogen rather than by weight alone. It feels firm and rubbery, sits directly behind and around the nipple, and is often tender when it first appears.
That is what separates it from simple fat, which is soft, spread more evenly across the chest and has no distinct disc behind the nipple. Many men have a mixture of both, and identifying the proportion is what decides how it should be treated. Fat responds to weight loss and to liposuction. Glandular tissue responds to neither.
Most cases are harmless. It matters because of the effect on confidence: shirts chosen to hide the chest, swimming avoided, gym work abandoned. Those are legitimate reasons to seek treatment and men should not feel obliged to justify them further.
It is one of the most common male chest conditions and appears in three distinct waves: in newborns, where it settles within weeks; in adolescence, where it is very frequent and usually resolves within two years; and in later adult life, where it becomes steadily more common with age, weight and medication use.
Adolescent cases that persist beyond two years rarely resolve on their own, and by that point the tissue has usually become fibrous rather than active.
The pattern of the swelling matters as much as its size, because it distinguishes glandular tissue from fat and both from anything more serious.
The underlying mechanism is always the same, a shift in the balance between testosterone and oestrogen. What differs is the reason for that shift.
Most cases are benign, but a few features make prompt assessment important rather than optional.
A hard, fixed, painless lump on one side, skin dimpling, nipple retraction, bloodstained discharge or a lump in the armpit should be assessed within days. Male breast cancer is uncommon but it exists, and these features must never be assumed to be simple tissue enlargement.
Assessment separates glandular tissue from fat, grades the severity and looks for an underlying cause that might be treatable in itself.
When it appeared, whether it is tender, how quickly it grew, and a careful review of medicines, alcohol, cannabis and any anabolic steroid use. Several causes are identified at this stage alone.
Distinguishing firm glandular tissue from soft fat, checking both sides, assessing skin quality and nipple position, and grading the severity from one to four.
Testosterone, oestrogen, LH, prolactin, thyroid, liver and kidney function where the history suggests a cause. Not every man needs the full panel, and testing is guided by the findings.
Ultrasound or mammography where a lump is one sided, hard or has any suspicious feature. Reassurance is worth having, and imaging is arranged promptly when there is any doubt.
Where a cause is found early, removing it can reverse the tissue. Stopping a responsible medicine, correcting low testosterone or stopping anabolic steroid use can all help if the tissue is still recent and tender. Once it has been present beyond a year or two it becomes fibrous, and at that point surgery is the only reliable route.
Surgery removes the gland and reshapes the chest in a single day care operation, often combined with male liposuction where fat is also contributing.
Cost depends on the grade, on how much gland and fat need to be removed, on whether skin needs tightening and on the anaesthesia used. Grade one and two cases are the least involved. Cases needing skin removal and nipple repositioning take longer and cost more. A single figure covering surgeon, theatre, anaesthesia, the compression garment and follow up is given after examination.
The right treatment depends on how long it has been present, what proportion is gland rather than fat, and whether a cause can be reversed.
Stopping or changing a responsible medicine, correcting low testosterone, reducing alcohol or stopping anabolic steroids. Most effective while the tissue is recent, tender and still growing.
Ask about thisLosing abdominal fat reduces the conversion of testosterone into oestrogen and improves chest contour. It will not remove glandular tissue, but it makes any subsequent surgery simpler.
Ask about thisSuitable where the chest is mostly fat with minimal gland. It contours well through very small incisions but leaves any firm disc behind the nipple untouched, so selection matters.
Ask about thisDirect removal of the glandular disc through a small incision at the areolar edge, combined with liposuction to blend the contour. The standard approach for the majority of men.
Ask about thisWhere the skin is loose and the nipple sits low, excess skin is removed and the nipple repositioned. This gives a far better shape in severe cases at the cost of longer scars.

Gynecomastia SurgeryStraight answers about this concern, written for men in Surat.
Ask a QuestionNot necessarily, and the difference decides the treatment. True glandular tissue feels like a firm rubbery disc directly behind the nipple, while fat is soft and spread across the whole chest. Many men have both, and examination establishes the proportion in a few minutes.
Weight loss reduces the fat component and improves the overall shape, sometimes substantially. It does not remove glandular tissue, which is why some very lean men still have a visible disc behind the nipple. Chest exercises alone do not remove either component.
In adolescence it very often does, usually within about two years. Beyond that the tissue becomes fibrous and rarely resolves. In adults, spontaneous resolution is uncommon unless a specific cause such as a medicine or steroid use is identified and stopped early.
It is very unlikely, but male breast cancer exists and is taken seriously in assessment. Warning features are a hard fixed lump on one side, skin dimpling, nipple retraction, bloodstained discharge or a lump in the armpit. Any of these prompts imaging without delay.
Only in a narrow window. Medicines can help when the tissue is recent, still tender and actively growing, and when an underlying hormonal cause is found. Once the tissue has matured into fibrous gland, no medicine reliably removes it.
Not usually, because the gland itself is removed and does not regrow. Recurrence is seen mainly in men who restart anabolic steroids, gain substantial weight or develop a new hormonal cause. Treating the underlying reason first protects the result.
Most of the work is done through a small incision at the lower edge of the areola, where the colour change hides the line well. Where skin must be removed for larger grades, the scars are longer, and their planned position is marked and agreed with you beforehand.
