When it comes to a growing lump in your armpit, especially one that has increased in size to over 3 centimeters, is painful upon pressure, and appears red, it is essential to take this situation seriously. While not all lumps are indicative of a severe condition, the characteristics you've described warrant a prompt evaluation by a healthcare professional.

Lumps in the armpit can arise from various causes, including swollen lymph nodes, cysts, infections, or even tumors. The fact that your lump is painful and has changed in size suggests that it could be related to an inflammatory process, such as an infection or an abscess. Lymph nodes in the armpit can swell due to infections in the arm, breast, or even systemic infections. In some cases, they can also swell due to more serious conditions, including malignancies.

Here are some key points to consider regarding your situation:
1. Pain and Redness: The presence of pain and redness around the lump is particularly concerning. These symptoms often indicate inflammation, which could be due to an infection. If the lump is an abscess, it may require drainage and antibiotic treatment.

2. Size and Growth: A lump that is growing in size, especially one that exceeds 3 centimeters, should not be ignored. Rapid growth can be a sign of a more serious underlying issue, and it is crucial to have it evaluated.

3. Associated Symptoms: Pay attention to any other symptoms you may be experiencing, such as fever, night sweats, weight loss, or fatigue. These could provide additional context for your healthcare provider.

4. Timing: Given that the lump has been observed for a week and is showing signs of growth, it is advisable to seek medical attention sooner rather than later. A healthcare provider will likely perform a physical examination and may recommend imaging studies, such as an ultrasound, to assess the lump further.

5. Potential Tests: Depending on the findings, your doctor may suggest a biopsy to determine the nature of the lump. This is particularly important if there is any suspicion of malignancy.

In summary, while not every lump in the armpit is a cause for alarm, the characteristics of your lump—its size, growth, pain, and redness—suggest that you should seek medical evaluation as soon as possible. Early diagnosis and treatment are crucial in managing any potential underlying conditions effectively. Do not hesitate to reach out to your healthcare provider for a thorough assessment and appropriate care.
