Swellings on the neck are more commonly known as thyroid nodules, lymph nodes, hemangiomas, sebaceous cysts, lipomas, and fibroids. Many tumors can grow, so a basic judgment needs to be made by appropriate examination or physical examination. For example, lymph nodes can be palpated with sliding or nodule-like manifestations by palpation. Sebaceous cysts are usually painful to touch, and a small black spot will be seen on the skin surface right above the tumor, and in severe cases, abscesses may break out. Lipomas are not painful to touch and have a distinct sliding sensation. In the case of thyroid nodules, the nodule is mainly growing in one part of the thyroid gland. Usually these tumors can be basically judged by ultrasound and then treated accordingly.
