Axillary tumor


I felt a lump under my armpit! The surface is flat and it doesn't hurt unless I press on it.
Could it be something serious?

Hello, Jinmu.
It is best for any lump to be evaluated in person by a physician, as its hardness is more related to malignancy than the presence of pain.
I hope you seek medical attention as soon as possible.
Thank you for your message.

When you discover a lump in your armpit, it can understandably cause concern. However, it’s essential to approach this situation with a clear understanding of what such lumps might indicate and the appropriate steps to take.

Firstly, lumps in the armpit can arise from various causes, and not all of them are serious. The most common types of lumps in this area include swollen lymph nodes, cysts, and lipomas (benign fatty tumors). Lymph nodes can swell due to infections, inflammation, or even benign conditions. For instance, if you have recently had a cold or an infection, it’s possible that your lymph nodes are reacting to that, leading to temporary swelling.

In your case, you mentioned that the lump is smooth, not painful unless pressed, and has a flat surface. These characteristics are often associated with benign conditions. Lipomas, for example, are soft, movable lumps that are generally painless and can be found in various parts of the body, including the armpit. They are composed of fat cells and are typically harmless.

However, it’s crucial to monitor the lump for any changes. If it grows larger, becomes painful, or if you experience other symptoms such as fever, night sweats, or unexplained weight loss, these could be signs that warrant further investigation. In such cases, it’s advisable to consult a healthcare professional for a thorough evaluation.

A healthcare provider may perform a physical examination and may recommend imaging studies, such as an ultrasound, to assess the lump further. In some instances, a biopsy may be necessary to rule out any malignant conditions, especially if there are concerning features associated with the lump.

It’s also important to consider your overall health and any other symptoms you may be experiencing. For example, if you have a history of cancer or other significant health issues, it may be prudent to seek medical advice sooner rather than later.

In summary, while many lumps in the armpit are benign and not a cause for alarm, it’s essential to stay vigilant. Regular self-examinations and awareness of any changes in the lump or your health are key. If you have any doubts or concerns, don’t hesitate to reach out to a healthcare professional for guidance. They can provide reassurance, conduct necessary tests, and help you understand the nature of the lump, ensuring that you receive appropriate care if needed. Remember, early detection and intervention are crucial in managing any health concerns effectively.
