Checking lymph can be registered with general surgery, but there are many diseases that cause lymphatic discomfort, such as respiratory infections, hematologic diseases, breast diseases, etc. It is necessary to choose different departments for examination according to different symptoms, and the details are as follows: 1. If the patient is accompanied by symptoms of respiratory tract infection, pain and fever, it may be caused by inflammation of lymph nodes. Patients should be registered with the respiratory department, and routine blood tests, x-ray examinations, and ultrasound examinations should be performed to clarify the cause for treatment. 2. If there are swollen axillary lymph nodes with symptoms of breast discomfort, they should be seen in the mammography department, or in the general surgery department if there is no mammography department. It may be caused by breast diseases such as mastitis, breast hyperplasia, breast cancer, etc. Ultrasound and CT of the chest should be performed to clarify the disease, and if there is a possibility of breast cancer, puncture biopsy should also be performed; 3. If there are no other symptoms but simple superficial lymph node enlargement, it may be caused by tumor.
