A neck lump is any lump, bump, or swelling in the neck.
Lump in the neck
There are many causes of lumps in the neck. The most common lumps or swellings are enlarged lymph nodes. These can be caused by bacterial or viral infections, cancer (malignancy), or other rare causes.
Swollen salivary glands under the jaw may be caused by infection or cancer. Lumps in the muscles of the neck are caused by injury or torticollis. These lumps are often at the front of the neck. Lumps in the skin or just below the skin are often caused by cysts, such as sebaceous cysts.
The thyroid gland may also produce swelling, or one or more lumps. This can be due to thyroid disease or cancer. Most cancers of the thyroid gland are extremely grow very slowly. They are often cured with surgery, even if they have been present for several years.
All neck lumps in children and adults should be checked right away by a doctor. In children, most neck lumps are caused by infections that can be treated. Treatment should start quickly to prevent complications or the spread of infection.
As adults age, the likelihood of the lump being a cancer increases. This is particularly true for people who smoke or drink a lot of alcohol. Most lumps in adults are not cancers.
If the lump is caused by a bacterial infection, you may need to take antibiotics. If the cause is a noncancerous mass or cyst, you may need surgery to remove it.
