Lumps Underarm: Causes and When to Seek Help - Surgery

More Info

Dear Patient,
Thank you for reaching out with your concerns regarding the lump you have discovered in your armpit. It’s understandable to feel anxious when encountering a new lump, especially when it is not accompanied by pain or other obvious symptoms. Let’s explore the possible causes of this lump and when you should seek medical attention.

Firstly, it’s important to recognize that lumps in the armpit can arise from various conditions. The most common causes include:
1. Lymphadenopathy: This refers to swollen lymph nodes, which can occur due to infections (like a cold or flu), inflammatory conditions, or even more serious issues like malignancies. Lymph nodes can become enlarged in response to infections in nearby areas, such as the arms or breasts.

2. Sebaceous Cysts: These are non-cancerous lumps that can form under the skin when sebaceous glands become blocked. They are typically painless unless they become infected.

3. Lipomas: These are benign tumors made up of fatty tissue. They are usually soft, movable, and painless.

4. Infections: Conditions such as abscesses can form due to bacterial infections, leading to painful lumps that may require drainage.

5. Fibroadenomas: Although more common in the breast, these benign tumors can occasionally be found in the axillary region.

6. Malignant Tumors: While less common, it is essential to consider the possibility of cancer, especially if the lump persists, changes in size, or is associated with other symptoms like weight loss, night sweats, or fever.

Given that you mentioned the lump is not painful and has persisted despite attempts to squeeze it, it is less likely to be an abscess or an infection, but it is still crucial to monitor it closely. Here are some recommendations on when to seek medical help:
- If the lump persists for more than two weeks: Any lump that does not resolve should be evaluated by a healthcare professional.


- If you notice changes: If the lump grows in size, becomes painful, or if you develop other symptoms such as fever, night sweats, or unexplained weight loss, it is essential to seek medical attention promptly.

- If you have a family history of cancer: If you have a family history of breast or other cancers, it is advisable to consult a physician sooner rather than later.

- If you experience other symptoms: If you notice any changes in your skin, such as redness, warmth, or discharge from the lump, these could be signs of infection or other conditions that require medical evaluation.

In conclusion, while many lumps in the armpit are benign and not a cause for concern, it is always best to err on the side of caution. I recommend scheduling an appointment with your healthcare provider for a thorough examination. They may perform imaging studies, such as an ultrasound, or a biopsy if necessary, to determine the nature of the lump.

Take care, and I hope this information helps alleviate some of your concerns. Please do not hesitate to reach out if you have further questions or need assistance.

Best regards.
