Cervical DNA is to check the cervical cells and rule out cervical cancer through cervical cell test, which is a relatively accurate test for cervical cancer screening. If you suspect cervical cancer, you need to go to the hospital for cervical DNA examination to determine the condition. If a large number of cells with abnormal DNA ploidy appear in the examination, cervical cancer is considered and cervical biopsy is needed. If there are only one or two abnormal cells, it is recommended to have a regular review once every six months. If cervical cancer is identified, it is better to treat it in time, so as not to cause cancer metastasis and affect the recovery of the disease. Early surgical treatment can be completely cured, but when it comes to the middle and late stages, it cannot be cured, and can only be reasonably treated with radiotherapy and chemotherapy drugs. Pay attention to vulvar hygiene, don’t have sex indiscriminately, and treat cervicitis and cervical erosion in time, so as not to cause malignant changes due to long-term inflammatory stimulation.
