It is good for oral tumor patients to eat light and nutritious food. Oral cancer patients usually try to eat more light food, eat more fresh vegetables and fruits, such as banana, green vegetables, radish, tofu, apple, pear, spinach or tomato, etc., which can promote intestinal digestion and regulate intestinal flora to a certain extent, and try to eat less cold, oily and greasy food, so as not to aggravate the condition. Oral tumor patients should keep a good attitude, actively cooperate with doctors for treatment, don’t be too anxious, and pay attention to drink more warm water, replenish a large amount of water, regulate their metabolic process, and pay attention to rest, ensure enough sleep time, and don’t be too tired. It is recommended that patients with oral tumor should go to the hospital for regular checkups, and once there is any abnormality, they should consult the doctor immediately.
