Painful Lump Under Right Armpit: When to Seek Medical Attention? - Oncology

When it comes to a painful lump under the right armpit, it is essential to approach the situation with caution and awareness of potential underlying issues. Given that you have experienced a similar lump in the past that resolved quickly, it may provide some reassurance; however, the persistence of the current lump for two to three weeks warrants further evaluation.

Firstly, it is important to consider the characteristics of the lump. You mentioned that it is painful when pressed but has not significantly changed in size or appearance. This could suggest a few possibilities, including a benign condition such as a swollen lymph node, a cyst, or a localized infection. Lymph nodes can become enlarged and tender due to various reasons, including infections (viral or bacterial), inflammation, or even stress on the body.
However, the fact that this lump has persisted for several weeks is a key factor. While some lumps can be benign and resolve on their own, any lump that lasts longer than a couple of weeks should be evaluated by a healthcare professional. This is particularly true if you experience any additional symptoms such as fever, night sweats, unexplained weight loss, or changes in your overall health. These symptoms could indicate a more serious condition that requires immediate attention.

In terms of next steps, I recommend scheduling an appointment with your primary care physician or a specialist, such as a dermatologist or an oncologist, depending on the initial assessment. During the consultation, the doctor will likely perform a physical examination and may recommend imaging studies, such as an ultrasound, to better understand the nature of the lump. In some cases, a biopsy may be necessary to rule out any malignancy, especially if there are concerning features.

In the meantime, it is advisable to monitor the lump for any changes in size, shape, or associated symptoms. Avoid pressing on the lump excessively, as this could lead to further irritation or inflammation. If you notice any rapid changes or if the pain worsens, seek medical attention promptly.

In summary, while the lump under your armpit may be benign, the duration and pain associated with it suggest that a medical evaluation is warranted. Early assessment can provide peace of mind and ensure that any necessary treatment is initiated promptly. Remember, it is always better to err on the side of caution when it comes to health concerns.
