What kind of doctor treats Breast Enlargement in Males?
Most people start with a primary care doctor, who can run basic tests and treat many causes directly. If surgery might be needed, the patient may be sent to a breast surgeon; some patients see an OB/GYN, who specializes in the female reproductive system and breast health.
What it is
Breast enlargement in males is called gynecomastia. It means the breast tissue grows larger than normal due to a shift in the body's hormone balance. The condition is common and usually not dangerous, but it can be uncomfortable or embarrassing. It is different from chest fat: in gynecomastia, actual gland tissue grows under the nipple.
Symptoms
The main symptom is a rubbery or firm lump of tissue under one or both nipples. The area may feel tender or sore, and the chest may look fuller. Pain, fluid leaking from the nipple, or a hard lump that does not move should be checked by a doctor soon.
Causes and who gets it
Hormone changes cause most cases. Boys going through puberty often have temporary breast growth, and older men can develop it as hormone levels fall. Health problems such as liver or kidney disease can play a role. Some medicines, including certain drugs for the heart, the prostate, or mental health conditions, can also cause breast tissue to grow, as can alcohol, marijuana, or anabolic steroids.
How doctors diagnose it
A doctor starts with a physical exam and questions about health, medicines, and habits. Blood tests may measure hormone levels, and imaging tests such as an ultrasound or mammogram may be used if the cause is not clear.
Treatment
Many cases need no treatment, as breast growth in teenage boys often goes away on its own within a few years. If a medicine is the cause, a doctor may suggest a different prescription, though no one should stop a prescribed drug without asking first. Surgery is an option when the growth does not shrink or causes lasting discomfort.
When to see a doctor
Anyone who notices a new lump in the chest should have it checked. Pain, quick swelling, fluid from the nipple, or a very hard lump deserve a prompt exam, even though these signs do not always mean something serious.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either one can do the physical exam, order blood tests, review medicines, and follow the condition over time, referring to a specialist when needed.
Common questions
Does gynecomastia go away on its own?
Often it does, especially in teenage boys. Puberty-related breast growth usually shrinks within a few years without treatment. Cases caused by medicines or health problems may improve once the cause is addressed.
Is breast enlargement in males a sign of cancer?
Usually it is not. Gynecomastia is benign, which means it is not cancer. Still, any new lump should be examined by a doctor so that serious causes can be ruled out.
Can exercise or weight loss fix it?
Losing weight can reduce fat in the chest, but it does not remove gland tissue. If the problem is true gland growth, exercise alone will not make it disappear.
Is surgery the only treatment?
No. Many cases need only watchful waiting. Some respond to medicines that affect hormone levels. Surgery is usually saved for cases that persist and bother the patient.
