There is a hard lump in the armpit?


Hello, Doctor: I have had hard lumps in my armpit for a long time, and there are several of them, but they are not painful or itchy! I previously had an ultrasound done, and they said to just monitor it, but recently I feel like there are more lumps appearing.
Can I go see a dermatologist for follow-up? Thank you.

If you haven't had a breast ultrasound in over six months, it is recommended that you schedule a breast ultrasound examination.

More Info


When it comes to hard lumps in the armpit, it's important to understand the potential causes and when to seek further medical evaluation. The presence of multiple hard lumps, especially if they are painless and not causing any discomfort, can often be benign. However, changes in the number or size of these lumps warrant a closer look.


Understanding the Lumps
1. Possible Causes: Hard lumps in the armpit can be due to several reasons, including:
- Lymphadenopathy: Enlarged lymph nodes can occur due to infections, inflammation, or even malignancies. The lymph nodes in the armpit can swell in response to infections in the arm or breast.

- Lipomas: These are benign tumors made of fat tissue and are generally soft and movable.

- Sebaceous Cysts: These are non-cancerous lumps that can occur due to blocked sebaceous glands.

- Fibromas: These are benign tumors that can develop in the connective tissue.

- Infections: Conditions like abscesses can also present as hard lumps.

2. Monitoring Changes: If you have been advised to monitor the lumps and they have increased in number or size, this is a significant change that should be evaluated. While many lumps are benign, any change in their characteristics can be a reason to consult a healthcare professional.


When to See a Specialist
1. Consulting a Dermatologist: Given that you have multiple lumps that are increasing in number, seeing a dermatologist is a reasonable step. A dermatologist can perform a thorough examination, possibly including imaging studies or a biopsy if necessary, to determine the nature of these lumps.

2. Signs to Watch For: You should seek immediate medical attention if you notice any of the following:
- Rapid growth of the lumps.

- Changes in color or texture.

- Development of pain, tenderness, or warmth in the area.

- Associated symptoms such as fever, night sweats, or unexplained weight loss.

3. Follow-Up: If your previous ultrasound indicated that monitoring was appropriate, it’s still wise to follow up, especially since you’ve noticed changes. Regular follow-ups can help catch any potential issues early.


Conclusion
In summary, while many hard lumps in the armpit can be benign, the fact that you have noticed an increase in their number is a valid reason to seek further evaluation. Consulting a dermatologist is a good choice, as they can provide specialized care and determine if any further action is needed. Always trust your instincts about your health; if something feels off, it’s best to get it checked out. Regular monitoring and communication with your healthcare provider are key to ensuring your health and peace of mind.
