Complex endometrial hyperplasia is generally called endometrial complex hyperplasia and is not a mid-stage cancer but a benign hyperplasia.
Complex endometrial hyperplasia is a kind of endometrial glandular hyperplasia, but the structure of the gland is complex and the mesenchyme is reduced, it belongs to the endometrial hyperplasia without atypical hyperplasia, i.e., the hyperplasia of the endometrial glandular cells does not have the heterotypic nature, which is a kind of benign hyperplasia, and it is not a cancer at this stage.
However, if endometrial hyperplasia with complexity continues to develop, there is a 3% chance that it will develop into endometrial cancer.
Therefore, if endometrial hyperplasia is detected, it is recommended to go to a regular hospital in time, complete the relevant examinations, clarify the cause of the disease under the guidance of a professional doctor, and take active targeted treatment to avoid delaying the condition.
