Known as unilateral gynecomastia, male breast asymmetry refers to the enlargement of breast tissue on only one side, leading to an uneven appearance. In this blog post, we will delve into the causes behind this condition, explore available treatment options, and shed light on possible risks associated with male breast asymmetry surgery.

Causes of Breast Asymmetry in Men

Breast asymmetry is a common condition that affects many men. In most cases, it is not a cause for concern and does not require medical attention. However, in some cases, breast asymmetry can be a sign of an underlying medical condition that needs to be addressed.

Hormonal Imbalances

One of the causes of this condition is hormonal imbalance. This occurs when there is an imbalance of estrogen and testosterone in the body. The imbalance can cause the breast tissue to grow, resulting in one, enlarged breast tissue being larger than the other. However, hormonal imbalances are only one side of the most common causes. Hormonal imbalances can occur due to a variety of factors, including puberty, medication, anabolic steroids, antidepressants, tricyclic antidepressants, antibiotics, alcohol, trauma, and breast tissue abnormalities.

Unilateral Gynecomastia

Unilateral gynecomastia, also known as asymmetrical gynecomastia, occurs when excess breast tissue or glandular tissue enlarges on only one breast and not on the other breast which can be on the left side or right side, causing an asymmetrical appearance. It is important to note that asymmetric gynecomastia can vary in severity, with some cases exhibiting minor differences while others are more noticeable.

While the exact reasons behind unilateral gynecomastia, particularly one-sided gynecomastia, remain unknown, there are several factors that could contribute to its development. Hormonal imbalances, such as elevated estrogen levels or decreased testosterone, play a significant role in breast tissue enlargement, which can make men develop gynecomastia. Conditions affecting the adrenal glands, liver, or testes can disrupt the hormonal balance and trigger the growth of excess breast tissue.

Trauma and Injuries

Trauma and injuries to fatty tissue in the nipple and chest area can also cause asymmetry in men's breasts. Trauma and injuries can cause damage to the breast tissue, which can lead to asymmetry.

Breast Tissue Abnormalities

Breast tissue abnormalities such as fibrocystic changes, breast tumors, breast abscess, and malignant breast mass are other possible causes. These conditions can cause one side of the tissue to become enlarged or lumpy, which can lead to asymmetry.

Genetics and Family History

Genetics and family history can also play a role in asymmetry in men. If there is a history of male breast cancer or asymmetry in the family, there is a higher chance of developing the condition.

Other Medical Conditions

Other medical conditions such as pseudogynecomastia, fat necrosis, skin irritation, cirrhosis, hyperthyroidism, malnutrition, starvation, heart disease, lung disease, and liver disease can also cause men to have breast asymmetry. These conditions can affect the hormone levels in the body, which can lead to male and female breast- asymmetry surgery too.

In conclusion, breast asymmetry in men can be caused by a variety of factors or one of the symptoms of diverse conditions, including hormonal imbalances, a gynecomastia surgery, trauma and injuries, breast tissue abnormalities, genetics and family history, and other medical conditions. is important to consult a medical professional if you notice any significant changes in the size or shape of your breasts.

Diagnosing Breast Asymmetry in Men

Breast asymmetry in men can be diagnosed through various tests and examinations. The following are the most common methods used by doctors to diagnose breast asymmetry in men:

Physical Exam

A physical exam is usually the first step in diagnosing breast asymmetry in men. During the exam, the doctor will look for any lumps, changes in size or shape, or other abnormalities in the tissue. The doctor may also check the lymph nodes in either side of the chest and armpit area for any signs of cancer.

Mammogram and Breast Ultrasound

A mammogram and breast ultrasound are imaging tests that can help detect breast asymmetry in men. These tests use X-rays or sound waves to create images of the breast tissue. A mammogram is usually recommended for men over the age of 50, while a breast ultrasound is recommended for younger men or men with dense breast tissue.


A biopsy is a procedure in which a small sample of breast tissue is removed and examined under a microscope for signs of cancer. A biopsy may be recommended if a lump or abnormality is found during a physical exam or imaging test.

Blood Tests

Blood tests are not typically used to diagnose breast asymmetry in men. However, they may be used to check hormone levels or to rule out other conditions that can cause male breast enlargement too, such as liver disease or thyroid problems.

Other Tests

In some cases, other tests such as magnetic resonance imaging (MRI) or a CT scan may be recommended to further evaluate breast asymmetry in men. These tests can provide more detailed images of the breast tissue and can help detect small lumps or abnormalities that may not be visible on a mammogram or ultrasound.

It is important to note that breast asymmetry in men does not always indicate cancer. However, it is important to seek medical attention and get full assessment if you notice any changes in your breast tissue. Early detection and treatment of breast cancer can greatly improve patient outcomes.

Treatment Options for Breast Asymmetry in Men

For men seeking a solution to their breast asymmetry, plastic surgeons offer various treatment options depending on the severity of the condition and individual circumstances. One common approach is liposuction, which involves removing skin excess and fat deposits from the affected breast to create a more balanced appearance. Overall, The best treatment option for bilateral asymmetry in any individual depends on the underlying cause of the condition, the severity of the asymmetry, and the individual's overall health.


Male breast asymmetry surgery is often the most effective treatment option to correct asymmetry. There are several surgical procedures that can be used, including:

  • Mastectomy: This is the surgical removal of breast tissue. It is often used for men with gynecomastia, a condition in which there is excessive breast tissue growth.

  • Liposuction: This is a procedure that removes excess fat from the breast area. Liposuction is often used for men with pseudogynecomastia, a condition in which there is excess fat but no breast tissue growth.

  • Breast reduction surgery: This surgery is also known as reduction mammoplasty. This male breast reduction surgery is performed to reduce the size and reshape the breasts. It is often recommended for people with disproportionately large breasts that cause physical discomfort, back and neck pain, posture problems, or emotional distress.


Medications can be used to treat breast asymmetry in men, although they are generally less effective than surgery. Some medications that may be used include:

  • Tamoxifen: This medication is often used for men with gynecomastia. It works by blocking the effects of estrogen in the body.

  • Hormone therapy: This involves taking medications that block the production of estrogen in the body. It is often used for men with hormonal imbalances that contribute to breast asymmetry.

  • Chemotherapy: This may be used for men with breast cancer that is causing breast asymmetry.

Preventive Measures

Preventive measures can help reduce the risk of developing breast asymmetry in men. These measures include:

  • Exercise: Regular exercise, such as running, swimming, or chest exercises, can help reduce excess fat and build muscle in the chest area.

  • Weight management: Maintaining a healthy weight can help reduce the risk of developing breast asymmetry.

  • Avoiding drugs and alcohol: Certain drugs and alcohol can contribute to breast asymmetry in men.

Breast Cancer

Breast cancer is a separate issue from breast asymmetry. However, if you have a family history of breast cancer, it is important to discuss this with your doctor before undergoing any breast-related medical procedures.


While breast asymmetry treatment can be effective in improving the appearance of the breasts, it is important to understand the potential complications and risks associated with the procedure.
