Endometrial hyperplasia is not the same as endometrial cancer; it can be treated promptly. Endometrial cancer develops from ongoing endometrial hyperplasia, which can progress into atypical hyperplasia, a precancerous condition of the endometrium. Further development can lead to endometrial cancer. Therefore, it is crucial to treat endometrial hyperplasia actively to prevent its progression to endometrial cancer. Endometrial hyperplasia results from a lack of progesterone influence, causing the endometrium to remain in a proliferative state rather than transitioning to the secretory phase. With the influence of progesterone, the endometrium would not undergo hyperplasia; therefore, treating endometrial hyperplasia with progesterone is advisable.
