Introduction  \nEndometrial cancer (EC) is 1 of 3 common malignant tumors of the female reproductive tract, exceeded by cervical cancer. It has an incidence rate ranging from 3% to 10% with an increasing trend in recent years.[1] About 65% of EC patients have no reproductive history. Surgery is the first choice for EC treatment, but it can lead to loss of fertility and affect the patient’s quality of life. This paper analyzes the data from 3 cases with early multi-focal EC which were treated by hysteroscopic surgery combined with progesterone in our hospital. Progesterone receptor was detected in lesion tissues, and patients had strong desires for fertility preservation. The clinical features, diagnostic parameters, and treatment measures are analyzed and summarized.  \nThe authors have no conflicts of interest to disclose.  \nThe datasets generated during and/or analyzed during the current study are available from the corresponding author on reasonable request.  \na Department of Obstetrics and Gynecology, The 964th Hospital, Changchun, Jilin Province, China, b Changchun University of Chinese Medicine, Changchun, Jilin Province, China.  \n* Correspondence: Li Wang, Department of Obstetrics and Gynecology,  \nThe 964th Hospital, Changchun, Jilin Province 130062, China (e-mail: [baihe199166@qq.com](baihe199166@qq.com)).  \n2.
