Enlarged lymph nodes in the neck with no painful pressure are not necessarily cancerous. This is because reactive hyperplasia of lymph nodes in the neck can also be enlarged lymph nodes and no painful pressure. Usually, the cause of lymph node enlargement needs to be identified and blood test or ultrasound examination is required. If it is only reactive hyperplasia and the change is small after 3-6 months of review, it can be considered as reactive hyperplasia caused by long-term pharyngitis, recurrent cough and recurrent upper respiratory tract infection. In the process of review, if symptomatic treatment is ineffective, the condition caused by lymphoma or metastatic gonorrhea of primary cancer in some parts of the body needs to be considered. Whether it is cancer is recommended to closely observe the changes, as well as regular check-ups at the hospital.
