The main recommendations are as follows: 1. TV thoracoscopic surgery is currently one of the standard modalities for mediastinal tumors. It mainly depends on the nature, size, specific location of the tumor, and the experience of the surgeon. 2.Some mediastinal tumors should be removed as early as possible even though they are asymptomatic. For one thing, as the tumor grows, compression symptoms will appear; for another, it is sometimes difficult to distinguish benign and malignant tumors by simple imaging and delay treatment; finally, some benign tumors may become malignant or have some immune diseases and other comorbidities. 3. I hope you can bring the information to the outpatient clinic for further consultation or treatment to avoid delaying the disease.
