This study employs a prospective cohort design by establishing a uterine cavity diseases research platform. The investigators will collect participants' current medical history, menstrual and obstetric history, past medical history, physical and gynecological examinations, imaging studies, laboratory tests, and pathological examinations. After the hysteroscopic surgery, the investigators will conduct a one-year follow-up on the disease progression of the participants. Through this comprehensive approach, the investigators aim to deeply investigate the pathogenesis, risk factors, and optimized treatment strategies for uterine cavity diseases.
