There is a hard lump in the armpit?


Hello, doctor.
I apologize for bothering you, but I would like to ask you some questions.
I originally had a hard lump in my right armpit for about two to three months.
After a while, I got busy and thought it was just a normal occurrence related to my menstrual cycle, so I didn't pay much attention to it.
Recently, I discovered that a smaller hard lump has also developed in my left armpit.
The lump on the right feels generally hard, while the one on the left is somewhat softer.
When the hard lump on the right first appeared, I assumed it was just a normal part of my menstrual cycle, but now that I see the left side has developed one too, I am a bit worried.
The hard lump on the right hasn't changed in appearance (it's about the size of a five-dollar coin), and it feels quite hard (I'm not sure if it has changed during this time).
It does not move, and both lumps are painful only when touched.
Should I be concerned about any potential risk factors? If I need to see a doctor, which specialty would be the most appropriate? Thank you for your help.

Hello: If you are concerned, you should schedule an appointment with a surgical specialist in breast surgery.
If the lump you mentioned is a lymph node, a biopsy will likely be arranged during the outpatient visit.
Thank you.

When it comes to lumps in the armpit, it's important to approach the situation with caution and awareness of the potential underlying causes. The presence of hard lumps, especially when they appear in both armpits, can be concerning and warrants further evaluation.
From your description, the lump on the right side has been present for about two to three months and feels hard, while the left side has a smaller, softer lump. The fact that both lumps are tender to touch and that the right lump does not move could indicate a few possibilities. Common causes of lumps in the armpit include swollen lymph nodes, cysts, or lipomas (benign fatty tumors). However, the characteristics you've described, particularly the hardness and tenderness, could also suggest an infection or inflammation in the area.

Lymph nodes can swell due to various reasons, including infections (like a cold or skin infection), autoimmune diseases, or even malignancies. The fact that the lump is painful when touched could suggest an inflammatory process, but it is essential to consider that not all swollen lymph nodes are indicative of serious conditions.
Given the duration and the changes you've noticed, it is advisable to seek medical attention. You should consider visiting a healthcare provider who specializes in this area, such as a primary care physician or a dermatologist. They can perform a thorough examination and may recommend imaging studies, such as an ultrasound, to better characterize the lumps. If necessary, they might also refer you to a specialist, such as an oncologist or a surgeon, depending on their findings.

In terms of when to seek medical advice, here are some guidelines:
1. Duration: If a lump persists for more than two weeks without improvement, it’s time to consult a doctor.

2. Size and Changes: If the lump increases in size, changes in texture, or if new lumps develop, seek medical advice.

3. Associated Symptoms: If you experience other symptoms such as fever, night sweats, unexplained weight loss, or persistent pain, these could be red flags that require immediate attention.

4. Pain: While some lumps can be benign and painless, any lump that is painful or tender should be evaluated.

In summary, while many lumps in the armpit can be benign, the characteristics you've described warrant a medical evaluation to rule out any serious conditions. Early diagnosis and intervention can be crucial, especially if there is an underlying issue that needs to be addressed. Don't hesitate to reach out to your healthcare provider for a thorough assessment.
