Hard Lumps Under the Nipple: Symptoms and Treatment

Nipple lump

Hello, I am a 17-year-old male.
A few weeks ago, I felt a hard lump under my left nipple, approximately 3 centimeters in diameter.
When I look in the mirror, the left breast appears slightly larger than the right.
Generally, there is no issue, but it hurts when touched, and applying pressure results in a little discharge.
What could these symptoms indicate? What examinations or treatments might be necessary?

Dr. Chen Jiaming reply Surgery

Males do have breast tissue, although it is smaller in volume.
Based on the context of male puberty, the lump you described is more likely to be normal breast tissue.
Generally, the size of the left and right breasts may not be the same, so one cannot assume there is an issue with the left breast solely based on it being larger.
If there is discharge upon squeezing, it is important to identify the characteristics and color of the discharge.
It is recommended that you consult a breast surgeon for a physical examination and relevant ultrasound imaging to confirm any issues.

More Info

Understanding hard lumps under the nipple can be concerning, especially for a 17-year-old male. The symptoms you describe, including a hard lump under the left nipple, slight enlargement of the left breast compared to the right, tenderness upon touch, and discharge upon squeezing, warrant careful evaluation.

In males, breast tissue can undergo changes due to various factors, including hormonal fluctuations, which are common during puberty. One possible condition that could explain your symptoms is gynecomastia, which is the enlargement of breast tissue in males. Gynecomastia can be caused by an imbalance between estrogen and testosterone levels, and it often presents as a firm lump under the nipple. It can be accompanied by tenderness and, in some cases, discharge.

Another possibility is a condition known as a breast cyst or a benign tumor, such as a fibroadenoma. These lumps are typically non-cancerous but can cause discomfort and may require monitoring or treatment depending on their size and symptoms. In rare cases, male breast cancer can present as a hard lump, especially if there are changes in the skin or discharge that is bloody or unusual.

Given your symptoms, it is essential to seek medical attention. A healthcare provider will likely perform a physical examination and may recommend imaging studies, such as an ultrasound or mammogram, to assess the lump further. Blood tests may also be conducted to evaluate hormone levels and rule out other underlying conditions.

Treatment will depend on the diagnosis. If it is determined to be gynecomastia, it may resolve on its own, especially if it is related to puberty. However, if the lump is persistent, painful, or causing significant distress, treatment options may include medications to address hormonal imbalances or, in some cases, surgical intervention to remove excess breast tissue.

In summary, while your symptoms may be related to common conditions like gynecomastia or benign breast lumps, it is crucial to consult a healthcare professional for an accurate diagnosis and appropriate management. Early evaluation can help alleviate concerns and ensure that any necessary treatment is provided.
