During radiotherapy, patients with advanced cervical cancer often have no major dietary contraindications. Normal diet and nutritious food are recommended. Cervical cancer is a common malignant tumor caused by human papillomavirus infection, heredity and other factors. Radiotherapy is one of the important treatments for cervical cancer, and the side effects during radiotherapy can cause certain consumption to patients. Dietary attention should be paid to eating more nutrient-rich foods, such as fish, beef, eggs and other high-protein foods. Patients are also advised to eat an appropriate amount of fresh vegetables and fruits every day to replenish vitamins, improve immunity and speed up disease recovery. Since radiotherapy may cause gastrointestinal discomfort, avoiding spicy and irritating foods is sufficient.
