For most of the early stage cervical cancer patients, there is no obvious change in menstruation, the volume, cycle and period of menstruation will not change, the only thing that has changed is vaginal bleeding after intercourse or after gynecological checkup. Therefore, if patients have these symptoms, they need to go to the hospital as soon as possible for gynecological checkups and cervical cancer screening TCT and HPV, and if problems are found, early colposcopy can detect lesions, diagnose and treat them at an early stage. However, if the stage of cervical cancer is late, there will be significant changes in menstruation at this time, such as an increase in the volume of menstruation or even heavy bleeding. Some of them may show prolonged and incomplete menstrual periods. Some may experience changes in the menstrual cycle, shortening of the menstrual cycle and frequent menstruation. Some patients also experience pain in the lower abdomen and even a foul odor of discharge.
