Persistent Lumps in the Armpit: When to Seek Medical Advice

I have a hard lump about 1.2 centimeters in size under my armpit that has been present for several years?

Several years ago (more than five years), I noticed a small hard lump under my right armpit.
It does not have any black spots, feels deep, and does not hurt when touched or pinched, but it protrudes when I raise my arm (approximately 1.2 cm in size).
After ignoring it, I found a similar hard lump on the left side, which feels like three small lumps connected together, with a total size of about 1.2 cm as well.
This has persisted for several years.
I would like to know what this condition might be and which specialty I should consult for further examination.
I previously visited a dermatologist, but the doctor did not indicate any danger and did not provide specific guidance on where to seek further observation.

Youzi / 27 years old / Female
1.
I would like to ask what this condition might be? A: Benign lymphadenopathy, lipoma? Accessory breast tissue? It's really hard to say without a thorough examination (inspection, auscultation, palpation, inquiry).

2.
Which department should I consult for a more appropriate examination? A: General surgery, especially breast surgery.

Wishing you good health,

More Info

When it comes to persistent lumps in the armpit, it's important to understand the potential causes and when to seek medical advice. Based on your description, you have noticed small, firm lumps in both armpits that have been present for several years. These lumps are not painful and do not have any concerning features such as discoloration or rapid growth.
Lumps in the armpit can arise from various causes, including:
1. Lymph Nodes: The armpit contains lymph nodes, which can become enlarged due to infections, inflammation, or other conditions. If the lumps are lymph nodes, they may swell in response to an infection or other immune response.

2. Lipomas: These are benign tumors made of fat tissue. They are usually soft, movable, and painless. Lipomas can occur anywhere in the body, including the armpit.

3. Cysts: Sebaceous cysts can form in the skin and may feel firm. They are generally harmless but can become infected.

4. Fibromas: These are benign tumors made of fibrous or connective tissue. They can also present as firm lumps.

5. Other Conditions: In some cases, lumps can be related to more serious conditions, including infections or malignancies.
Given that you have had these lumps for several years without significant changes, it is less likely that they are indicative of a serious condition, but it is still important to monitor them.

When to Seek Medical Advice
You should consider seeking medical advice if you notice any of the following changes:
- Rapid Growth: If the lumps start to grow significantly in size over a short period.

- Pain or Discomfort: If the lumps become painful or tender.

- Changes in Appearance: If the skin over the lumps changes color, becomes red, or shows signs of infection (such as warmth or discharge).

- Systemic Symptoms: If you experience unexplained weight loss, fever, night sweats, or fatigue.

Which Specialist to See
Since you have already consulted a dermatologist without significant findings, the next step would be to see a healthcare provider who specializes in conditions related to the lymphatic system or general surgery. Here are some options:
1. Primary Care Physician (PCP): Your first step can be to consult your PCP, who can perform a physical examination and determine if further evaluation is necessary.

2. General Surgeon: If the lumps are suspected to be lipomas or cysts, a general surgeon can evaluate them and discuss options for removal if necessary.

3. Hematologist: If there is a concern about lymph nodes or any hematological issues, a hematologist can provide specialized care.

4. Oncologist: If there is any suspicion of malignancy, an oncologist can perform further evaluations and provide treatment options.

Conclusion
In summary, while the lumps you describe may not be immediately concerning, it is essential to remain vigilant and seek medical advice if any changes occur. Consulting with a primary care physician or a specialist can provide clarity and peace of mind. Regular monitoring and open communication with your healthcare provider are key to managing your health effectively.
