Laryngeal cancer patients should eat light, easy-to-chew and easy-to-digest food after radiotherapy, such as rice soup and soft noodles. Laryngeal cancer patients are prone to discomfort such as pain in swallowing or difficulty in swallowing, so they should pay attention to adjusting their diet structure in general. They can choose some light, soft and easy-to-digest foods, such as rice soup, fish soup, egg custard, rotten noodles and so on. Attention should also be paid to increase protein-rich foods such as fish, lean meat, eggs, milk, etc. Meat can be pureed with a cooking machine to help swallowing and digestion.
