Therefore, drinking milk after esophageal cancer surgery is good for patients’ recovery, especially for improving patients’ immunity, and also for adjuvant radiotherapy and chemotherapy after surgery. However, if some patients’ intestinal function has not fully recovered after surgery, drinking pure milk may cause diarrhea and other gastrointestinal discomfort, and even cause intestinal flora imbalance. If this is the case, pure milk should be drunk sparingly, mainly with light, easily digestible food. When the patient’s intestinal function is restored, the amount of milk can be gradually increased.
