It is obvious to get concerned when you discover any new lump on neck. Good news is that, most of the cases of lumps on the neck are acute and harmless. However, sometimes lumps on the neck may be the presentation of more serious condition that may need immediate medical attentions.

Your body has many lymph nodes that plays key role in fighting off the virus, bacteria and other illnesses. Among all the areas, most common areas that you may notice swollen lymph nodes are neck, underarms and groin. Most of the lymph nodes in our body can’t be felt; they can only be felt during illness. In normal healthy person they are non-tender or painless. During illness they may be tender and swollen. In this article we’ll focus on lumps that arises in different location of the neck and their possible causes.

Lump below the jaw
Any lump below the jaw on either side may be due to swelling of the submandibular lymph node. Swelling occurs when there is infection of the head, neck, pharynx, ears, eyes, and scalp.

Lump below Chin
Any lump below the chin may be due to swelling of submental lymph node. Swelling occurs due to various conditions and disease like infectious mononucleosis, cytomegalovirus, Epstein-Barr virus, toxoplasmosis, dental pathology such as periodontitis.

Lump above the right clavicle
When there is any lump above the right clavicle, there may be something wrong with the lungs or the esophagus. When there is swollen right supraclavicular lymph node, it may suggest cancer of the lung or the stomach.

Lump above the left clavicle
Lump above the left clavicle may suggest lymphoma or thoracic cancer, while sometime it just may be due to fungal or bacterial infection.

Lump on back of neck
Lump on back of neck may just be due to local infection in the head or neck region. However, if the lumps are either side of the back of neck, they might also be due to lymphoma, tuberculosis or any head and neck cancer.

The most common causes of painful lump in the neck are due to infection and usually are self-limited and can resolve quickly after infection is controlled. However, some lumps can lasts longer for several months and can create confusion with the cancer. Experts agree that the lumps above the clavicle (supraclavicular) should be immediately investigated for cancer.

Risk factors for malignancy include the followings:

  • Old age
  • Firm, fixed and hard lump on neck
  • Painless
  • Duration more than 2 weeks
  • Supraclavicular location

Visit your doctor (especially ENT doctor) if you have any unexplained lumps on the neck. He/she will perform a though examination and when there are no any specific signs and symptoms of any serious disease or malignancy, your doctor may keep you on observation for a month. If the lesion still persists, he/she may perform biopsy or other specific tests.

If you are experiencing persistent enlargement of lymph nodes that lasts more than 2 weeks or if they feel hard and painless, you should get it checked immediately. Don’t rely on what you have learned and seen on the internet and try to diagnose yourself. Get it checked and confirm its benign nature so you don’t have to regret later.

    I actually had a friend who developed one of these “tumors” they had to remove it before they could tell what it was. Turns out it wasn’t anything harmful.

    He had waited a while before he went in. and lately they found a bacteria in his heart! I hope they aren’t related.

    I have a lump in the left side of my neck. My mom says that its just mumps. But its painful as hell. It hurts when I laugh. It hurts when I lie down. I don’t know what it really is. My mom said that theres nothing to worry about. But I feel like its not just mumps.

    I have a lump just below my chin and further down my neck and I don’t know if it is anything harmful. I haven’t had any other side effects like feeling ill of pain but I’m still a bit worried. Also considering there are two, could it mean it has spread and is something more worse than just a little lump?

    I have one decent sized lump around the posterior cervical area; it’s painless, a bit squishy and can be moved under the skin slightly. I would say it’s just a part of the neck or something but I’ve only noticed it now and I feel like it’s gotten a little bit bigger over the past week. Well obviously I hope it’s not what I think it is, but I guess I’ll check with the doctor about it. No other symptoms. I just got type 1 diabetes and a collapsed lung recently, I really could do with a little calm.
