Bleeding one week after menstruation is not necessarily cervical cancer, the early clinical symptom of cervical cancer is the possibility of coitus, which leads to contact bleeding. If bleeding occurs one week after menstruation, it is mostly caused by ovulation bleeding, which is mainly due to the decrease of hormone level during this period, and the endometrium is more sensitive to the decrease of hormone level, and retreating bleeding occurs, and most of the bleeding will be cleared up by itself in about three days. If this situation occurs in the clinic, there may also be endometrial inflammation, pelvic tumors or cancer of the cervix, which may lead to irregular vaginal bleeding, so it is necessary to go to the hospital to give a checkup. If you have not been screened for cervical cancer in the past year, you can do cervical cancer screening as soon as possible to rule out the possibility of cervical cancer and find out whether there is any abnormality in the endometrium through ultrasound, and give treatment according to the results.
