In cervical cancer with menstruation, the main patients are women of childbearing age, and the menstrual period is generally still regular. We know that menstruation is caused by changes in the ovarian function of the ovarian tube. In the days of normal menstruation, the volume is more and the period has cleared, but due to the congestion of the lesion of the cervix, some blood may continue to flow. So it makes the vaginal bleeding longer and makes the patient feel that her period may be prolonged than usual. The patient has been diagnosed with cervical cancer and the doctor will recommend early treatment. Those who are able to have surgery as soon as possible and those who cannot have surgery do further treatment such as radiotherapy. All these treatments will affect menstruation. Therefore, menstruation should not be very confusing for a patient with cervical cancer.
