Thyroid cancer is not allowed to drink alcohol after surgery, because alcohol is the primary factor in the causative factors of most cancers, and it ranks first, and tobacco and alcohol are basically as the main triggering factors of various malignant tumors, so thyroid cancer, as a kind of malignant tumors, is not recommended to drink alcohol after surgery either. The reason why patients love to drink alcohol is not clear, and the possibility of going back towards recurrence is higher in the case of drinking alcohol, so if patients are more fond of drinking alcohol, it is still recommended to quit drinking alcohol before it is too late, so as to ensure that thyroid cancer can be cured.
