The concept of having a hard bump on the neck without pain, i.e., the presence of a neck swelling, is relatively broad and can be a common manifestation of neck or non-neck diseases. Common causes of neck swelling include acute or chronic lymphadenitis, lymph node tuberculosis, purulent infection of soft tissues in the neck; or thyroid lesions such as goiter, thyroid adenoma; skin lesions such as skin cysts; some blood disorders or tumors can also lead to a hard pack in the neck. If necessary, biopsies should be taken for pathological examination to clarify the nature of the mass and to distinguish whether it is benign or malignant, and then deal with it accordingly. In most cases, the size and growth rate of neck masses have nothing to do with benignity or malignancy, so they need to be treated in a timely manner at the hospital. If the mass is large and accompanied by high fever and pain, it should be considered as an inflammatory disease or other easily diagnosed and managed disease. Therefore, when a lump or swelling is found in the neck, it should be closely observed and promptly treated at a hospital.
