What does this mean?
Not every lump in the neck is a lymph gland. Salivary glands, cysts you were born with, fatty tissue and the structures lying between the muscles can all produce a bump you can feel. What carries the information, though, is less what the lump is than how it behaves: how long it has been there, the way it has grown, what it feels like to touch, and whether it moves when you press on it.
Three details set this picture apart from a swollen gland. A gland reacting to infection is tender, slides under your finger, and goes down within a few weeks once the source has cleared. The lump described here is painless, feels hard, stays fixed to the deeper tissue instead of sliding when you press, and has either stayed the same for weeks or grown slowly. The absence of pain is not counted as a good sign. Being painless is one of the features that makes this picture a suspicious one.
This description is not a diagnosis on its own. Some lumps with exactly these features turn out to be harmless. The distinction is made by examination with the hands, by ultrasound and, where needed, by a needle biopsy. It cannot be made by waiting or by looking at a photograph. If you smoke or drink, have had treatment to the head and neck before, or have a sore in your mouth that is not healing, it is advised that the assessment is not put off.
Behind this kind of lump there may be conditions arising from the mouth, from a salivary gland or from the neck itself. The headings below are not in order of likelihood; they work more like a map of which speciality takes over.
Likely causes
What helps at home?
- Measure the lump once and note it down together with when you first noticed it. After that, do not check it by hand several times a day, because that both spoils any proper tracking and feeds the worry.
- Do not try taking an antibiotic on your own judgement to see what happens. When a hard, painless lump does not shrink on an antibiotic, all that is left is two lost weeks.
- Do not massage the lump, apply heat to it or try to drain it with a needle. These attempts alter the tissue and can make the later assessment harder.
- Take a written list to the appointment of how much you smoke and drink, the operations and treatments you have had, and the medicines you take. It speeds the assessment up.
- If the lump has been there for three weeks, or has grown within that time
- If the lump feels hard, gives no pain and does not move when you press on it
- If it comes with hoarseness lasting weeks, difficulty swallowing, or one-sided pain that runs to the ear
- If you have a sore or a patch in your mouth or on your tongue that has not healed in two weeks
- If unexplained weight loss, night sweats or a long-lasting temperature have also joined the picture
Frequently asked questions
- Isn't it a good sign that it does not hurt?
- No. Pain is most often the mark of infection, and glands swollen by infection are tender. Lumps that grow quietly, on the other hand, take longer to be noticed and so are assessed later. That is why being painless is a reason to bring the assessment forward, not a reason to wait.
- How many weeks is it reasonable to wait?
- A gland that has swollen after an infection is usually given two to four weeks to go down. But if the lump described here is painless and hard, the fact that it has reached three weeks is on its own a reason for assessment. Where a lump has appeared without any clear sign of infection and is growing, there is no need to wait for that period to pass.
- Which clinician should I see?
- Lumps in the neck are assessed by ear, nose and throat and by head and neck surgery, and that is where the decision on imaging and, if needed, a biopsy is made. The dentist's contribution sits at a different point: to see whether the lump has a source inside your mouth, to identify it if there is one, and, if there is not, to send you to the right place without delay.
