When cervical cancer reaches the middle stage, the main symptoms are irregular vaginal bleeding or bleeding after sexual intercourse, increased vaginal discharge, sometimes purulent and bloody, and foul odor if there is infection. During ultrasound, it can be seen that the cervical area is thickened and enlarged, and there is an inhomogeneous mass, and the patient may show lower abdominal pain. At the middle stage, surgery is usually not possible, and surgery is not clean. At this time, radiation therapy or radiotherapy plus chemotherapy can be used. Therefore, if you have abnormal vaginal discharge, you should go to the hospital for examination as soon as possible, and pre-cancerous screening of the cervix must be done.
