Dry mouth and sore throat are the most common radiation reactions in radiotherapy for many tumor patients, which are caused by radiation damage to salivary glands and mucous membranes. So how should the radiotherapy diet of cervical cancer patients be adjusted? According to the patient's current symptoms, eat a cold, non-irritating diet and avoid hard and rough food. The temperature of food should not be too hot, meat should be finely cut, and vegetables or fruits can be squeezed into juice if they can't be swallowed. For patients with severe dry mouth and sore throat, a small amount of lidocaine solution can be taken or swallowed before meals, and it has synergistic effect on radiotherapy, which can effectively prevent complications and obviously relieve pain.
