Cervical lymph nodes

Hello, doctor.
There is a lymph node located below my left ear in the neck that has been present since childhood.
Additionally, there are two lymph nodes in the left side of my neck that have also existed for a long time.
These three lymph nodes sometimes enlarge due to fatigue, colds, or severe inflammation of the scalp hair follicles, but they are generally about 1 cm in size, and their firmness can change.
After a while, they tend to soften and shrink.
Recently, I have been experiencing inflammation in my wisdom teeth and gum pain for several days, and these three lymph nodes have enlarged a bit again.
Based on your assessment, are these lymph nodes benign? Furthermore, there is a lymph node located above the one near my ear, and I feel some pain when pressing on the bone behind my ear.
I can only feel a slight protrusion upon careful palpation, and it is not very noticeable visually.
I am unsure how long it has been there.
Is this also benign, or is it just a structural variation?

Hello: When experiencing lymphadenopathy, most people worry and ask if it is "lymphoma" or a benign "inflammatory response" or "lymphoid hyperplasia." The clinical differentiation methods are as follows: 1.
Cancer typically grows rapidly, often doubling in size within about two weeks.
2.
Cancerous lymph nodes are usually painless and just enlarge (even if they grow larger than 5 cm, they remain painless).
3.
Conditions like colds, fatigue, or exhaustion do not affect cancer cells; they continue to grow regardless of external conditions.
4.
Cancerous lymph nodes often feel firmer to the touch.
5.
Lymphoma is often accompanied by symptoms such as daily fevers, night sweats, and unexplained rapid weight loss.
Based on your description, I do not think it is malignant lymphoma; it may be benign lymphoid hyperplasia.
If you are concerned, it is best to visit a hematologist at the hospital.
Let the doctor examine you and consider having blood tests done.
Thank you!

When it comes to understanding lymph nodes in the neck, it’s essential to recognize that lymph nodes are a normal part of the immune system. They play a crucial role in filtering lymph fluid and housing immune cells that help fight infections. The presence of lymph nodes in the neck is common, and many people have lymph nodes that can be felt, especially when they are swollen due to various reasons.

In your case, you mentioned having lymph nodes that have been present for a long time, typically around 1 cm in size, and that they fluctuate in size and consistency based on factors like fatigue, infections, or inflammation. This is a typical response of lymph nodes to various stimuli, such as infections or inflammation in nearby areas, like your gums or scalp. When the body is fighting an infection, lymph nodes can swell as they produce more immune cells to combat the pathogens.

The fact that your lymph nodes have been stable in size and have returned to their normal state after episodes of swelling is a reassuring sign. Generally, lymph nodes that are soft, mobile, and less than 1 cm in size are often considered benign, especially if they respond to infections and inflammation. In your case, since the lymph nodes have been present for a long time and have shown a pattern of swelling and shrinking, they are likely reactive rather than malignant.

Regarding the lymph node located near your ear, the tenderness you feel when pressing on the bone behind your ear could indicate a few things. It could be related to the lymph node itself or possibly an issue with the surrounding tissues, such as muscle strain or inflammation. If this lymph node is also soft and mobile, it is likely benign. However, if you notice any significant changes in size, consistency, or if it becomes painful, it would be wise to consult a healthcare professional for further evaluation.

In terms of when to worry about lymph nodes, there are several red flags to consider:
1. Size: Lymph nodes larger than 1 cm that do not decrease in size over time may warrant further investigation.

2. Consistency: Hard, fixed lymph nodes that do not move freely can be concerning.

3. Duration: Lymph nodes that remain swollen for an extended period (more than a few weeks) without any signs of infection should be evaluated.

4. Associated Symptoms: Unexplained weight loss, night sweats, fever, or persistent fatigue accompanying swollen lymph nodes can be signs of a more serious condition.

If you experience any of these concerning signs, it is essential to seek medical advice. A healthcare provider may recommend imaging studies or a biopsy to rule out any serious conditions, including malignancies.

In summary, based on your description, the lymph nodes you have mentioned appear to be benign, especially since they have been present for a long time and fluctuate in size with infections. However, it is always best to monitor any changes and consult with a healthcare professional if you have concerns. Regular check-ups can help ensure that any potential issues are addressed promptly.
