The 5-year survival rate of thymic carcinoma can reach 60%-70%. Thymic carcinoma is an inert cancer and has a longer survival period after resection. Especially after early surgery, the 10-year survival rate of thymic carcinoma can reach 80%-90%. Therefore, if a lump is found in the thymus gland, it should be removed as early as possible, especially if the lump is larger than 1 cm, it should be removed early and pathological examination should be performed. In case of early thymic carcinoma, it should also be checked whether there is invasion around it, and if there is invasion, radiotherapy and chemotherapy should also be given after surgery to improve the success rate of surgery and prolong the life span of patients.
