Over time, menstrual cycles often become regular; however, persistently irregular menstruation warrants further investigation. Serious conditions, such as endometrial cancer, which is often linked to prolonged unopposed estrogen exposure, can be prevented with timely detection. We report a case involving a 27-year-old obese, nulliparous woman with a history of prolonged irregular menstrual bleeding since menarche. She had not undergone regular health checkups and had never been properly evaluated until multiple admissions for severe anemia prompted further investigation, which confirmed the diagnosis of endometrial carcinoma. Delays in seeking care for abnormal menstrual bleeding resulted in serious outcomes. Endometrial carcinoma may significantly reduce future fertility potential. Therefore, primary healthcare providers play a pivotal role in educating and raising public awareness about this frequently under-recognized issue, as timely investigation for early recognition is paramount.<\/jats:p>","DOI":"10.4082\/kjfm.25.0163","type":"journal-article","created":{"date-parts":[[2025,12,26]],"date-time":"2025-12-26T07:38:22Z","timestamp":1766734702000},"page":"274-278","update-policy":"https:\/\/doi.org\/10.4082\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Endometrial
