Lumps in the Armpit: Symptoms and Causes Explained - Oncology

More Info

---

Understanding lumps in the armpit can be concerning, especially when accompanied by pain and other symptoms. The presence of multiple hard lumps, along with a small growth resembling a granulation tissue or a wound, can indicate several underlying conditions. It is essential to consider the symptoms you described: pain when pressing on the area, discomfort while sleeping, and pain during arm movement.

Possible Causes of Armpit Lumps
1. Lymphadenopathy: One of the most common causes of lumps in the armpit is swollen lymph nodes. Lymph nodes can become enlarged due to infections (like bacterial or viral infections), inflammatory conditions, or malignancies. If the lumps are tender and painful, it may suggest an acute infection or inflammation.

2. Infections: Skin infections, such as abscesses or folliculitis, can lead to painful lumps in the armpit. These infections can cause localized swelling, redness, and tenderness. If the lump is warm to the touch or there is pus, it may require drainage and antibiotics.

3. Cysts: Sebaceous cysts or epidermoid cysts can form in the armpit area. These are generally benign and can be painless unless they become inflamed or infected. They may feel like soft lumps under the skin.

4. Lipomas: These are benign tumors made of fatty tissue. They are usually painless and soft to the touch. However, if they grow larger, they can cause discomfort, especially if they press against surrounding tissues.

5. Granulation Tissue: The small growth you described that resembles granulation tissue could be a result of irritation or injury in the area. Granulation tissue typically forms during the healing process of wounds and can be sensitive to touch.

6. Malignancy: Although less common, lumps in the armpit can be a sign of breast cancer or lymphoma. If the lumps are hard, fixed, and painless, or if there are other systemic symptoms (like weight loss, night sweats, or fever), it is crucial to seek medical evaluation promptly.


Symptoms to Monitor
Given your symptoms of pain when pressing on the lumps, discomfort during sleep, and pain with arm movement, it is essential to monitor for any additional symptoms, such as:
- Changes in the size or shape of the lumps
- Redness or warmth in the area
- Fever or chills
- Unexplained weight loss
- Night sweats

Recommended Actions
1. Consult a Healthcare Provider: It is vital to see a healthcare provider for a thorough evaluation. They may perform a physical examination, review your medical history, and possibly order imaging studies (like an ultrasound) or a biopsy to determine the nature of the lumps.

2. Avoid Irritation: Until you can see a doctor, try to avoid any activities that may irritate the area, such as tight clothing or excessive movement that causes pain.

3. Pain Management: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, may help alleviate discomfort temporarily.

4. Keep the Area Clean: Maintain good hygiene in the armpit area to prevent any potential infections from worsening.


Conclusion
In summary, lumps in the armpit can arise from various causes, ranging from benign conditions to more serious issues. Given the symptoms you've described, it is crucial to seek medical attention to obtain an accurate diagnosis and appropriate treatment. Early evaluation can help rule out serious conditions and provide peace of mind.
