a Small Neck Tumor: Is It Genetic or Viral?

Inquiry about a small tumor on the left posterior side of the neck?

Hello Doctor, I have noticed a small lump about 0.7 cm in diameter on the left posterior side of my neck.
It feels somewhat hard, round, and has a bit of elasticity.
It does not move, and pressing it firmly does not cause much pain.
This has persisted for over 5 years, and its size has remained relatively stable.
I remember that when I first discovered it, it was larger and could be seen when looking straight ahead, but now it is more noticeable when I lower my head.
Sometimes it feels hard, and other times it feels a bit soft.
I would like to know if this could be malignant or if it is a congenital issue.
When I first found the lump, my father also discovered that he had a similar one in the same location, which is larger than mine, about 1 cm, and more swollen, clearly visible to the naked eye.
He has already undergone surgical removal, and the excised lump resembled a clump of straw.
Can lumps like this be hereditary, or could it be that my father and I contracted the same virus, leading to the simultaneous development of these lumps? Thank you, Doctor.

Hello,
1.
Is it malignant? Or is it congenital?
A: If it were malignant, it wouldn't have been asymptomatic for five years.
As for whether it is congenital, the answer to this question depends on your perspective.
Essentially, it may not have been present since childhood, or it cannot be verified whether it has been there since childhood.
Do you believe that something congenital must be present from a young age?
2.
Can tumors be hereditary?
A: They likely are not.
3.
I and my father were infected with the same virus, so did we develop it around the same time?
A: This cannot be verified.
Wishing you peace and joy,

More Info

When it comes to small neck tumors, particularly those that have been present for an extended period, there are several factors to consider in determining whether they are benign or malignant, as well as their potential genetic or viral origins. Based on your description of a small, hard, round, and somewhat elastic lump in your neck that has persisted for over five years without significant change, it is likely that this tumor is benign.
Benign tumors, such as lipomas or lymph nodes, often exhibit characteristics like being movable, painless, and stable in size over time. The fact that your lump has not changed significantly in size or characteristics over five years is a reassuring sign. Malignant tumors, on the other hand, typically present with rapid growth, changes in texture, pain, or other systemic symptoms such as weight loss or fever.
Your mention of a similar lump in your father's neck raises an interesting point regarding genetic predisposition. Certain types of tumors can indeed have a hereditary component, meaning that if one family member has a particular type of tumor, others may also be predisposed to developing similar conditions. However, this does not necessarily mean that the tumors are malignant or that they will behave in the same way.
In terms of viral infections, some tumors, particularly lymphomas or certain types of head and neck cancers, can be associated with viral infections, such as Epstein-Barr virus (EBV) or human papillomavirus (HPV). However, the presence of a stable, non-painful lump for several years does not strongly suggest a viral etiology. If both you and your father developed similar lumps around the same time, it could be coincidental, or it could suggest a genetic predisposition rather than a viral infection.

If you are concerned about the nature of your tumor, it is advisable to consult with a healthcare professional who can perform a physical examination and possibly recommend imaging studies or a biopsy. A biopsy would provide definitive information regarding the cellular makeup of the tumor and whether it is benign or malignant.
In summary, while your lump appears to be benign based on its characteristics and duration, the familial aspect raises the possibility of a genetic predisposition. It is essential to monitor any changes in the lump and consult with a healthcare provider for further evaluation if you have concerns. Regular check-ups can help ensure that any changes are addressed promptly, providing peace of mind and maintaining your health.
