Left Neck Mass: Lymph Node or Tumor Concerns?

Left posterior cervical mass?

Hello, I would like to ask about a slightly raised area on the back of my left neck, just a bit behind the left side of my neck, which is about 1 to 2 centimeters in size.
It seems to be immovable.
I remember discovering it about ten years ago and consulted a physician at Mackay Memorial Hospital, who said it was nothing to worry about.
Recently, I have had a cold with nasal congestion and yellow phlegm, and it seems that the raised area has become a bit more swollen.
Could this be a lymph node or a tumor? Should I go to a larger hospital for further examination, and which department should I consult? Thank you.

This is usually part of the posterior auricular lymph nodes, which may become more swollen during a mild infection, such as when there are nearby pimples.
If the swelling persists for more than a week or continues to enlarge, please seek medical attention promptly.

When it comes to a left neck mass, particularly one that has been present for an extended period and has recently increased in size, there are several important considerations to keep in mind. Based on your description, the mass is located in the left posterior neck area, measures approximately 1-2 cm, and has been noted to be somewhat immobile. Given these characteristics, it is essential to assess whether this mass is a lymph node or a tumor, as well as to determine the appropriate next steps for evaluation and management.

Firstly, it is important to understand that lymph nodes can become enlarged for various reasons, including infections, inflammatory conditions, or malignancies. In your case, the recent symptoms of a cold, nasal congestion, and yellow phlegm suggest that there may be an underlying infection, which could lead to reactive lymphadenopathy. Reactive lymph nodes are typically tender, mobile, and associated with systemic symptoms like fever or localized signs of infection. However, if the lymph node is hard, immobile, and has been present for a long time, it raises the possibility of other conditions, including tumors.

The fact that you have had this mass for over a decade without significant changes is reassuring, but the recent increase in size warrants further investigation. It is advisable to consult with a healthcare professional, ideally an Ear, Nose, and Throat (ENT) specialist, who can perform a thorough examination and may recommend imaging studies such as an ultrasound or CT scan. These imaging modalities can help characterize the mass further, providing information about its size, shape, and any associated features that might suggest malignancy.

If imaging studies raise concerns about the nature of the mass, a fine needle aspiration (FNA) biopsy may be indicated. This procedure involves using a thin needle to extract cells from the mass for cytological analysis, which can help determine whether the mass is benign or malignant. It is crucial to follow up on this if advised by your physician, as early detection of malignancy can significantly improve treatment outcomes.

In summary, while the mass you describe may be a reactive lymph node due to a recent infection, the increase in size and immobility are concerning features that should not be ignored. Consulting with an ENT specialist is the best course of action, as they can provide a comprehensive evaluation and guide you through the necessary diagnostic steps. Early intervention is key, especially if there is any suspicion of malignancy, so do not hesitate to seek further medical attention.
