During chemotherapy for colon cancer, the following foods can be eaten: 1. Eat more light and soft foods that are easy to digest, such as light noodles, rice soup, rice porridge, vegetable soup and so on. 2. Take more vitamins and fiber, such as green vegetables, corn, apples, sweet potatoes and so on. 3. You can eat foods such as figs and ginger because they can improve the vomiting caused by the side effects of chemotherapy and promote the digestive ability of the spleen and stomach. During the chemotherapy period after colon cancer surgery, you should also exercise more to strengthen your body and improve your immune system.
