Patients with oral cancer should pay special attention to their diet to ensure they are providing their body with added nutrition. Consuming milk, chicken soup, fish soup, and porridge can help supplement nutrients. Additionally, consuming more vitamins by eating fruits and vegetables can enhance the patient's resistance. If the diet is further complemented with high-protein, high-vitamin, high-calorie, and low-fat foods, it can facilitate a quicker recovery. During the treatment of oral cancer, besides taking medications, patients should also be mindful of their diet and maintain a positive and optimistic outlook, which can greatly assist in the treatment of the disease.
