A round hard thing in the neck may be a soft tissue lesion in the neck, enlarged lymph nodes or thyroid nodules.
1. Soft tissue lesions in the neck: Soft tissue lesions in the neck, such as lipomas and sebaceous cysts, can cause lumps in the neck.
2. Enlarged lymph nodes: Lymph nodes exist in the neck in large numbers, such as inflammation can cause hyperplastic lymph node enlargement, tumor causing metastatic lymph node enlargement and so on, leading to the appearance of lumps in the neck.
3. Thyroid nodules: enlarged nodules in the thyroid gland can also cause lumps in the neck, which need to be further examined in the hospital to confirm the diagnosis.
Lumps in the neck need to be further examined to determine their location, nature and size, so you should go to the hospital in time for an examination to clarify the cause and provide symptomatic treatment.
