Axillary lump


Hello, doctor! I have noticed a hard lump in my armpit that hurts when pressed, but it doesn't hurt when left alone.
I can only feel the lump when I raise my arm, and it is about 0.5 to 1 centimeter in size.
Which specialist should I see? Thank you!

When it comes to discovering a lump in the armpit, it is important to approach the situation with caution and awareness. The presence of a hard lump that is painful when pressed but not when at rest can be indicative of several conditions, some of which may require medical attention.
Firstly, the lump you are describing could be a swollen lymph node. Lymph nodes are small, bean-shaped structures that are part of the lymphatic system, which plays a crucial role in the body’s immune response. They can become enlarged due to various reasons, including infections, inflammation, or even malignancies. Infections in the arm, breast, or even systemic infections can cause nearby lymph nodes to swell.
Another possibility is that the lump could be a benign cyst or lipoma. Cysts are fluid-filled sacs that can develop in various parts of the body, while lipomas are soft, fatty lumps that are generally harmless. Both of these conditions are typically not serious, but they can sometimes cause discomfort or concern due to their appearance or the sensation they produce.

Given that the lump is painful when pressed, it is advisable to consult a healthcare professional. You should consider seeing a primary care physician or a specialist in internal medicine. They can perform a physical examination and may recommend further diagnostic tests, such as an ultrasound or a biopsy, if necessary. If the lump is determined to be related to lymph nodes, you might be referred to an ear, nose, and throat (ENT) specialist or an oncologist, depending on the findings.

It is also important to consider accompanying symptoms. If you experience fever, night sweats, unexplained weight loss, or persistent pain, these could be signs of a more serious condition that warrants immediate attention.
In summary, while a lump in the armpit can often be benign, it is crucial to have it evaluated by a healthcare professional to rule out any serious conditions. Early diagnosis and intervention can lead to better outcomes, especially if the lump is related to an underlying health issue. Therefore, I recommend scheduling an appointment with your primary care physician as soon as possible to discuss your symptoms and receive appropriate care.
