Thymoma has a low degree of malignancy and has a good treatment effect, so there is no need to worry too much. Thymoma is a tumor that occurs in the anterior mediastinum and usually has no symptoms in the early stage, and is mostly found by chance during physical examination. Once discovered, thymoma should be surgically removed in time. If early thymoma is treated with surgery in time, it can achieve better curative effect, and the ten-year survival rate can reach about 90%. Although the degree of malignancy of thymoma is low, thymoma can invade the surrounding tissues, lymph node metastasis or distant metastasis. At this time, there is a risk of recurrence after surgical resection, which should be supplemented with radiotherapy and chemotherapy. After surgery, patients with thymoma should undergo regular checkups and enhance exercise, eat a balanced diet and avoid exertion in daily life to help their body recover as soon as possible.
