Armpit Lumps: When to Seek Medical Advice - Oncology

Axillary lump


Hello, I would like to inquire about a hard lump approximately one centimeter in size that I discovered under my left armpit while showering a few days ago.
It is located on the tissue above the joint, and I had recently shaved the area.
When pressed, it feels like a single lump and is painful, although it does not hurt normally.
Additionally, it can move with the surrounding tissue.
Should I see a doctor, or is there any self-examination I should perform?

It is recommended to consult with a general surgeon or a plastic surgeon.

When it comes to discovering a lump in the armpit, such as the one you described, it is essential to approach the situation with caution and awareness. The presence of a lump can be concerning, and while many lumps are benign (non-cancerous), some may require further evaluation to rule out serious conditions.


Understanding Armpit Lumps
Armpit lumps can arise from various causes, including:
1. Lymph Nodes: The armpit contains lymph nodes that can become swollen due to infections, inflammation, or other medical conditions. If the lump feels firm and is tender to the touch, it may indicate an infection or inflammation.

2. Cysts: These are fluid-filled sacs that can develop in the skin or deeper tissues. They are usually harmless but can become painful if they become infected.

3. Lipomas: These are soft, fatty lumps that are generally harmless and painless. They can move slightly under the skin when pressed.

4. Infections: Conditions such as folliculitis (inflammation of hair follicles) or abscesses can cause painful lumps in the armpit area.

5. Tumors: Although less common, lumps can also be indicative of tumors, both benign and malignant.

When to Seek Medical Advice
Given your description of a one-centimeter hard lump that is painful when pressed but not painful otherwise, it is advisable to consult a healthcare professional for the following reasons:
- Duration and Changes: If the lump persists for more than two weeks, changes in size, or if you notice additional symptoms such as fever, night sweats, unexplained weight loss, or changes in skin color over the lump, you should seek medical attention.

- Pain and Mobility: While the lump is movable, which is often a good sign, the fact that it is painful when pressed warrants further evaluation. Pain can indicate inflammation or infection, which may require treatment.

- Self-Examination: While you can perform a self-examination by checking for any changes in size, shape, or texture of the lump, it is crucial not to rely solely on self-assessment. A healthcare provider can perform a more thorough examination and may recommend imaging studies (like an ultrasound) or a biopsy if necessary.


What to Expect During a Medical Evaluation
When you visit a healthcare provider, they will likely:
1. Take a Medical History: Discuss your symptoms, duration of the lump, any recent infections, or other relevant health issues.

2. Perform a Physical Examination: The doctor will examine the lump and surrounding areas to assess its characteristics.

3. Order Tests: Depending on the findings, they may recommend blood tests, imaging studies, or a biopsy to determine the nature of the lump.


Conclusion
In summary, while many armpit lumps are benign, it is essential to err on the side of caution. Given your symptoms, it would be wise to consult a healthcare professional for a thorough evaluation. Early diagnosis and treatment can help address any underlying issues and provide peace of mind. Remember, it’s always better to seek medical advice when you notice changes in your body, especially when it comes to new lumps or bumps.
