The second radiotherapy needs to be considered according to the severity of the disease and whether the patient can tolerate it, which is possible, but it is recommended to strictly follow the doctor’s instructions. Radiotherapy is to eliminate the local tumor through local treatment with radiation, but a series of radioactive injuries will occur in the process of radiotherapy, including local skin redness, swelling and ulcers, fever, nausea and vomiting, bone marrow suppression, etc., and it will also harm the normal human tissues, which belongs to the more hazardous treatment modality. Therefore, the second radiotherapy needs to meet the conditions of tumor recurrence, patient’s ability to tolerate radiation, longer time from the first radiotherapy, etc. Due to the serious side effects of radiotherapy, it is necessary to actively cooperate with doctors to receive standardized treatment.
