Tumor treatment is like a long march, every step of success is worth celebrating and is the result of the joint efforts of patients, families and doctors. You and your friends around you should have more or less the following problems in your treatment, which will not only affect your treatment, but also must bother your life. These include: food loss (anorexia); mouth and throat ulcers; dry mouth; tooth and gum problems; changes in taste and smell; nausea; vomiting; diarrhea; constipation; fatigue (feeling tired all day); and depression. When you are faced with these problems, do you feel that there is nothing you can do, or that the simple advice of your doctor is simply not effective. Then remember to come to a clinical dietitian and we will help you through dietary restructuring, dietary behavior modification and nutritional therapy. Remember, you have a clinical dietitian to fight with you to get rid of the tumor!
