We express the mass screening data of uterine cervical cancer, endometrial cancer, and ovarian cancer in Japan. The increase in cervical cancer mass screening rate, correlate well with decreasing mortality for uterine cancer, but mortality is re-increasing now. It is concern to increase of uterine cervical dysplasia and cervical cancer of young women. Then, we need to start the screening for more young women. The detect ratio of uterine corpus cancer is increasing now. Then, we need to change the object, and introduce new screening method for example, trans vaginal echogram. Ovarian cancer screening method is not establishment, but mortality rate in patients with ovarian cancer will be increase in future. Trans vaginal echogram is the better method for the screening. On the economical reason, we have a tendency the cancer screenings are neglected. It is important to watch the policy of health carefully.
