Increased secretion after radiotherapy for cervical cancer is normal if it is clearer in texture and has no peculiar smell, and it is enough to follow the doctor’s instruction to strengthen vaginal douche. If accompanied by pus, blood pain, etc., it is considered that inflammation or cancer has not been cleared completely, and it is necessary to consult doctor for further diagnosis in time. Radiotherapy is a more effective treatment for cervical cancer. When patients receive radiotherapy, the necrotic tumor material will be shed and the radiation will stimulate the normal tissues, which may lead to increased secretion, which is a normal phenomenon. It is necessary to follow the doctor’s instruction to perform daily vaginal douching to prevent infection and adhesion. The shedding of necrotic tissue and the increase in secretion provide a favorable environment for bacteria to survive and reproduce, which can easily lead to pelvic inflammation after radiotherapy. If the secretion is accompanied by pus, blood, pain or odor, etc., it is necessary to consult a doctor in time for further treatment according to the specific situation. In addition, failure to remove the cancerous lesions may also lead to increased secretion. Therefore, radiotherapy should follow the doctor’s instruction of strict vaginal douching, and if abnormal secretion occurs, it is necessary to consult a doctor in time to clarify the cause for treatment.
