When is Endometrial Thickness Considered Abnormal?
An endometrial thickness outside the expected range for a specific phase of the menstrual cycle or life stage might be considered abnormal. For premenopausal women, a thickness greater than 16 mm in the secretory phase could raise concerns. For postmenopausal women, a thickness exceeding 5 mm may necessitate further investigation, particularly to rule out endometrial cancer.
