Armpit Lumps: When to Seek Medical Attention - Oncology

More Info

---

When it comes to lumps or bumps in the armpit area, it’s important to understand the potential causes and when to seek medical attention. The lump you described, which is small, firm, and skin-colored, could be a variety of things, including a benign condition or something that requires further evaluation.


Common Causes of Armpit Lumps
1. Lymphadenopathy: The armpit (axillary) region contains lymph nodes that can become swollen due to infections, inflammation, or malignancies. If the lump is a swollen lymph node, it may indicate an underlying infection (like a cold or skin infection) or, less commonly, a more serious condition.

2. Sebaceous Cyst: These are non-cancerous lumps that can form under the skin when a sebaceous gland becomes blocked. They are usually painless and can sometimes become infected, leading to pus formation.

3. Abscess: If you noticed pus when you squeezed the lump, it could be an abscess, which is a collection of pus that can occur due to infection. Abscesses often require drainage and antibiotic treatment.

4. Fibroadenoma: Though more common in breast tissue, these benign tumors can occasionally occur in the axillary region. They are usually firm and movable.

5. Lipoma: A lipoma is a benign tumor made of fat tissue. They are typically soft, movable, and painless.


When to Seek Medical Attention
Given that your lump has persisted for about ten days without significant change in size, it is advisable to consult a healthcare professional. Here are specific signs that warrant immediate medical attention:
- Persistent Growth: If the lump continues to grow or change in size, it should be evaluated.

- Pain or Discomfort: If you experience increasing pain, tenderness, or discomfort in the area.

- Fever or Systemic Symptoms: If you develop fever, chills, or other systemic symptoms, this could indicate an infection that needs treatment.

- Changes in Skin: If the skin over the lump becomes red, warm, or starts to drain pus, this suggests an infection that may require antibiotics or drainage.

- Family History of Cancer: If you have a family history of breast cancer or other cancers, it’s prudent to have any new lumps evaluated.


What to Expect at the Doctor's Office
When you visit your healthcare provider, they will likely perform a physical examination of the lump and may ask about your medical history, any associated symptoms, and any recent infections or illnesses. Depending on their findings, they may recommend:
- Imaging Studies: An ultrasound or mammogram may be performed to get a better look at the lump.

- Fine Needle Aspiration or Biopsy: If there is concern about the nature of the lump, a sample may be taken for further analysis.

- Blood Tests: To check for signs of infection or other underlying conditions.


Conclusion
While many armpit lumps are benign and may not require treatment, it’s essential to err on the side of caution. Given that your lump has not resolved and has shown signs of infection, it would be wise to seek medical attention. Early evaluation can help rule out serious conditions and provide peace of mind. Always trust your instincts; if something feels off, it’s better to get it checked out.
