Cervical cancer usually has no obvious precursor symptoms, but it may have symptoms such as increased vaginal discharge, vaginal bleeding and other organ involvement. 1. Increased vaginal secretion: Early stage of cervical cancer may have white or bloody secretion with fishy odor, and in late stage may have a large amount of slop-like and purulent leukorrhea. 2. Vaginal bleeding: patients with cervical cancer may have the symptom of painless irregular vaginal bleeding, if the cancer invades large blood vessels, it will cause hemorrhage, which will be life-threatening in serious cases. 3. Involvement of other organs: when the cancer invades the bladder, it will cause symptoms of bladder irritation such as frequent urination and painful urination; when the cancer presses the rectum, it may cause symptoms of acute and severe pain; in the advanced stage of the disease, it may cause symptoms of anemia, emaciation and malignant fluid. It is suggested that patients should go to the hospital for consultation in time and carry out relevant treatment strictly under the guidance of physicians.
