Lymphadenopathy (inflammation? tumor)

Hello, I recently discovered a swollen lymph node in the lower left side of my neck.
It is painless to the touch, round and flat in shape, and the doctor estimated it to be about 0.3 cm, although I feel it might be around 0.8 cm (based on surface area, it protrudes about 0.3 cm).
I have visited two ENT specialists; the first one said it was inflammation, while the second one smiled and said not to worry, but both prescribed anti-inflammatory medication.
After finishing the medication about a month ago, the swelling has neither increased nor decreased significantly.
I have come across a lot of information suggesting that swollen lymph nodes can indicate tumors, but since my body shows no other abnormalities and my upper respiratory tract is normal, this situation is affecting my daily life.
I would appreciate your advice on the following questions:
1.
Can lymph node inflammation be painless and persist without resolution?
2.
If there has been no increase in size over a long period, can I disregard it?
3.
Is 0.3 cm a normal size for a lymph node? It feels like a noticeable protrusion, even though it is not visibly apparent.
The doctor smiled but still prescribed anti-inflammatory medication?
4.
Should I go to a major hospital for further examinations?
5.
Does my situation resemble that of a tumor?
Thank you for your generous explanation.
Thank you, thank you.

Hello: Based on your description, if what you felt is a lymph node, a normal, non-inflamed lymph node typically does not cause pain and generally does not lead to any discomfort.
It is often discovered accidentally, and its size may not change significantly.
If it remains the same size over a long period, it likely indicates a benign condition, and usually, it is sufficient to just monitor it without excessive concern.
However, if the size increases or if there is pain or inflammation, it would be advisable to seek evaluation at a hospital.
In terms of size, lymph nodes with a diameter of less than 1 cm are mostly benign and normal.
Clinically, anti-inflammatory medications or antibiotics may be prescribed if there is inflammation, which can lead to improvement, and inflamed lymph nodes typically decrease in size after the infection resolves.
If the lymph node is normal and non-inflamed, its size may not change significantly.
Regarding tumors, they generally refer to enlarged tissues; however, based on your description, it seems to be a normal lymph node, and there should be no concern about malignancy.
If you are still worried, it is advisable to consult a physician at a major hospital for a definitive diagnosis.
Wishing you peace and health.
Sincerely, Dr.
Jue-Yi Cheng, ENT Specialist, Taoyuan Hospital, Department of Health.

Understanding lymph node enlargement can be a source of anxiety for many individuals, especially when faced with conflicting medical opinions. In your case, the left cervical lymph node enlargement you described raises several important considerations.

1. Pain and Inflammation: It is indeed possible for lymph nodes to be enlarged due to inflammation without being painful. Lymph nodes can react to various stimuli, including infections, inflammation, or even benign conditions. The fact that your lymph node is not painful and has remained stable in size after a month of anti-inflammatory treatment suggests that it may not be a cause for immediate concern. However, persistent enlargement, even without pain, warrants careful observation.

2. Stability of Size: If the lymph node has not increased in size over the past month, this is a positive sign. Many benign lymph nodes can remain enlarged for an extended period without indicating malignancy. If there are no accompanying symptoms such as fever, night sweats, or unexplained weight loss, the likelihood of a serious condition decreases significantly.
3. Size Considerations: A lymph node measuring 0.3 cm is generally considered within the normal range, although the perception of size can vary based on individual assessment. The fact that it feels prominent to you does not necessarily indicate a problem. The physician's lighthearted response may reflect their confidence in the benign nature of the finding. The prescription of anti-inflammatory medication could be a precautionary measure to address any underlying inflammation.

4. Further Evaluation: If you continue to feel uneasy about the lymph node, it may be beneficial to seek a second opinion or consult a specialist at a larger medical facility. A thorough evaluation could include imaging studies such as an ultrasound or CT scan, which can provide more detailed information about the lymph node's characteristics. Additionally, if there is still concern, a fine needle aspiration (FNA) biopsy could be performed to rule out malignancy definitively.

5. Differentiating from Tumors: The characteristics of your lymph node—its size, shape, and lack of pain—are more consistent with benign conditions rather than malignancy. Tumors typically present with more concerning features, such as rapid growth, firmness, and associated systemic symptoms. However, it is essential to remain vigilant and monitor any changes in the lymph node's characteristics.

In summary, while your lymph node enlargement is likely benign, it is crucial to maintain open communication with your healthcare providers. Regular follow-ups and monitoring are essential, especially if any new symptoms arise or if there are changes in the lymph node's size or consistency. Trusting your healthcare team and seeking further evaluation if needed can help alleviate your concerns and ensure your peace of mind.
