In short. How common male breast enlargement is, why most of it is physiological, and the specific features that mean it should be assessed rather than ignored.
Key points
- Having it looked at does not commit you to surgery.
- An assessment answers two questions: is there anything here that needs medical attention, and what is the tissue made of.
- Many patients are reassured and need nothing further.
The first useful thing to say about enlargement of the male breast is that it is common. It affects a large share of adolescent boys and a substantial number of adult men. It is also, in the great majority of cases, a normal physiological response to a change in hormone balance rather than a disease. The reason it does not feel common is that men rarely mention it, and that silence is why so many patients arrive at a consultation years later than they needed to.
Why it happens
Breast tissue in men responds to the balance between oestrogen and androgen. When that balance shifts — as it does in puberty, in older age, and in a number of other situations — the tissue can enlarge. In adolescence this is expected and usually temporary. In older men it becomes more common again. Weight gain contributes to the fatty component, and a number of medicines and some medical conditions can contribute as well.
The features that mean it should be assessed
Most enlargement is a soft or firm disc of tissue beneath the areola, present on both sides, that has been there for a long time or appeared gradually. The features that change the picture are different: enlargement that has appeared recently rather than gradually; enlargement on one side only; a lump that is hard, irregular or fixed rather than a disc beneath the areola; discharge from the nipple; a change in the skin over the chest; or pain that is severe or worsening.
Assessed is not the same as operated
Having it looked at does not commit you to surgery. An assessment answers two questions: is there anything here that needs medical attention, and what is the tissue made of. Many patients are reassured and need nothing further.
What an assessment is looking for
It looks for two separate things. The first is whether anything needs investigating in its own right, which is why the history and examination matter more than the appearance. The second is what the tissue is made of — glandular tissue, fat, or a mixture — because that decides whether an operation can help and which one. Neither question can be answered reliably from a photograph or from a description.
Reasons to be seen sooner rather than later
- A lump that is hard, irregular or fixed, or that is not typical of a disc beneath the areola.
- Nipple discharge, or a change in the skin of the chest or areola.
- Enlargement that has appeared recently, is worsening, or is present on one side only.
What to do next
Arrange an assessment rather than researching operations. Bring a complete list of your medicines, including anything bought without a prescription and any supplements, because that list is part of the assessment. Bring the timeline: when it started, how it has changed, whether it is tender, and whether either side differs. With that, a clinician can tell you whether anything needs investigating and what your options actually are — including the option of waiting, which for many patients is the correct answer.
Frequently asked questions
How common is gynecomastia really?
Very common. It affects a large proportion of adolescent boys and a substantial number of adult men, and most of those cases are a normal response to hormone change rather than a disease. The reason it feels rare is that men rarely discuss it, not that it is unusual.
Does it usually go away?
In adolescence it commonly settles over one to three years without treatment. In adults, enlargement that has been present and stable for years is less likely to resolve on its own, because the tissue has matured. Either way, an assessment is how you find out which situation you are in.
What specifically should prompt an assessment?
Enlargement that has appeared recently rather than gradually, enlargement on one side only, a lump that is hard or irregular or fixed rather than a soft disc beneath the areola, discharge from the nipple, skin changes over the chest, or pain that is severe or getting worse. Those features need looking at rather than watching.
Risks & Limitations
- Fluid collecting under the skin, which is one of the most common problems after chest surgery and may need draining.
- Residual glandular tissue beneath the areola if it is not completely removed, which can look like the original problem persisting.
- Contour irregularities, including a depression where tissue was removed or a difference between the two sides.
- Numbness or altered sensation of the nipple and the surrounding skin, which is common and may not fully recover.
- Bleeding or a blood collection that may require a return to theatre, and infection or delayed wound healing, both more likely in smokers.
- Skin loss at the edge of an incision, which is uncommon and more likely where a large area has been undermined.
- Permanent scars that may widen, thicken or stay red.
- Recurrence where a contributing medicine, substance or medical condition was not addressed.
- No operation can guarantee a perfectly flat chest, identical sides or invisible scars.
When to Seek Care
- A lump in the chest that is hard, irregular or fixed rather than a soft disc beneath the areola.
- Discharge from the nipple, or a change in the skin of the chest or areola.
- Fever, or redness, warmth, pain or discharge that is spreading from the incision.
- A swelling under the skin that is new or increasing, or fluid leaking from the wound.
- An area of skin or the areola that turns dark, or pain that your medication does not control.
