Cervical cancer, endometrial cancer and ovarian cancer are the three major malignant tumors of the female reproductive system. The main symptom in 90% of patients with endometrian cancer is abnormal vaginal bleeding.

Women of childbearing age have increased menstrual flow, irregular vaginal bleeding, endless menstruation, and postmenopausal bleeding in older women should be paid attention to. Studies have shown that 15%-20% of endometricrial cancer patients are infertile. This is because estrogen stimulates endometrium hyperplasia, which can gradually become cancerous.
