Armpit Lumps: When to Seek Further Medical Evaluation

Axillary lump

Hello doctor, I recently discovered a small hard lump in my armpit.
It doesn't hurt when I touch it, but I didn't have this lump before, and it is only present on one side.
The color is somewhat red.
I had a breast ultrasound done last month, and at that time, the examination showed no issues, and I didn't notice the lump in my armpit.
Should I undergo further examination for this?

If you are very young and do not wish to have a mammogram, please consult a breast surgeon first.
Thank you for your letter.

When it comes to discovering a lump in the armpit, it is essential to approach the situation with caution and awareness. The presence of a hard lump, particularly if it is new, warrants further evaluation, especially if it is accompanied by changes in color or texture, such as redness. While many lumps can be benign, such as swollen lymph nodes, cysts, or lipomas, it is crucial to rule out more serious conditions, including infections or malignancies.

Given your description of the lump being hard, non-painful, and red, there are several potential causes to consider. One common reason for a lump in the armpit is lymphadenopathy, which refers to swollen lymph nodes. This can occur due to various reasons, including infections (like viral or bacterial infections), inflammatory conditions, or even malignancies. The fact that you had a chest ultrasound last month without any issues is reassuring, but it does not completely rule out the possibility of a new development.

Here are some factors to consider when deciding whether to seek further medical evaluation:
1. Duration and Changes: If the lump has been present for more than a couple of weeks, or if it has changed in size, shape, or color, it is advisable to consult a healthcare provider. Changes in the characteristics of the lump can indicate a need for further investigation.

2. Associated Symptoms: Pay attention to any accompanying symptoms. If you experience fever, night sweats, unexplained weight loss, or fatigue, these could be signs of a more serious condition and should prompt immediate medical attention.

3. Physical Examination: A healthcare provider will perform a physical examination to assess the lump's characteristics, including its size, consistency, mobility, and tenderness. They may also check for other swollen lymph nodes in the neck, groin, or other areas.

4. Imaging Studies: Depending on the initial evaluation, your doctor may recommend imaging studies, such as an ultrasound or a CT scan, to get a better view of the lump and surrounding tissues.

5. Biopsy: If there is any suspicion of malignancy or if the lump does not resolve, a biopsy may be necessary. This involves taking a small sample of tissue from the lump for laboratory analysis.

6. History of Cancer: If you have a personal or family history of cancer, particularly breast cancer or lymphoma, this may increase the urgency for evaluation.

In summary, while not all lumps are cause for alarm, the presence of a new, hard, and red lump in the armpit should be evaluated by a healthcare professional. It is better to err on the side of caution and seek medical advice. Your doctor can provide a thorough assessment and determine if any further tests or treatments are necessary. Regular follow-ups and monitoring are essential, especially if the lump persists or changes over time.

It is likely folliculitis or a sebaceous cyst. It is recommended to observe for a few days (get plenty of rest, drink plenty of water, and keep the underarm area dry and clean). If there is no improvement, consider seeing a dermatologist or a plastic surgeon.
