a 2cm Lump Under the Areola: Causes and Solutions - Surgery

A flat 2 cm lump located beneath the areola?


When I was 14 years old, the left areola had a similar issue that resolved on its own, but it wasn't as large.
Now, the right areola has developed a lump that is bigger than before.
Is this gynecomastia? The lump is painful when I press on it, and after observing it for a month, it hasn't increased in size.
Additionally, there are a few small bumps around the areola that look like miniature acne.
How should I handle this? Thank you, doctor.

Hello! It is recommended to see a general surgeon.
Most cases of gynecomastia are indeed in males, but other tumors must also be ruled out.
Take care! Changhua Hospital is concerned about you!

When it comes to a lump under the areola, especially in a male, there are several potential causes to consider. Given your age and the description of the lump, it is essential to approach this with a clear understanding of the possible conditions and the appropriate steps to take.

Firstly, the lump you are describing could be related to a condition known as gynecomastia, which is the enlargement of breast tissue in males. Gynecomastia can occur due to hormonal changes, particularly an imbalance between testosterone and estrogen levels. During puberty, it is common for boys to experience fluctuations in hormone levels, which can lead to temporary breast tissue enlargement. This condition is often benign and may resolve on its own over time.

The fact that you mentioned the lump is painful and has not increased in size over the past month is a positive sign, as it suggests that it may not be a serious issue. However, the presence of small bumps resembling acne around the areola could indicate a condition known as Montgomery tubercles, which are normal sebaceous glands that can become more prominent during puberty.

To address your concerns, here are some steps you can take:
1. Observation: Since you have already been monitoring the lump for a month without significant changes, continue to observe it. Look for any changes in size, shape, or associated symptoms such as increased pain or discharge.

2. Avoid Manipulation: Try to avoid pressing or manipulating the lump excessively, as this can lead to irritation or inflammation.

3. Consult a Healthcare Provider: If the lump persists, increases in size, or if you experience additional symptoms such as discharge from the nipple, significant pain, or changes in the surrounding skin, it is crucial to consult a healthcare provider. A doctor can perform a physical examination and may recommend imaging studies or other tests to determine the nature of the lump.

4. Hormonal Evaluation: If gynecomastia is suspected, your doctor may suggest hormonal evaluations to check your testosterone and estrogen levels. This can help identify any underlying hormonal imbalances that may need to be addressed.

5. Treatment Options: If the lump is diagnosed as gynecomastia and is causing significant discomfort or psychological distress, treatment options may include medication or, in some cases, surgical intervention. However, many cases resolve without treatment.

6. Education and Support: Understanding that hormonal changes during puberty can lead to various physical changes can be reassuring. If you feel anxious or concerned about your body image, consider discussing these feelings with a trusted adult or a mental health professional.

In summary, while the lump under your areola could be related to gynecomastia or normal developmental changes, it is essential to monitor it closely and seek medical advice if you have any concerns. Early evaluation and intervention can help ensure that any underlying issues are addressed appropriately. Remember, it is always better to err on the side of caution when it comes to your health.
