Question: is 10 mm endometrial thickness normal?
Answer: The risk of cancer is approximately 4.6% in postmenopausal women with vaginal bleeding if the endometrium measures 5 mm or greater (see upper arrow, Table 2). In women without vaginal bleeding, a threshold of 10 mm (i.e. ≤ 10 mm is considered normal) is associated with a similar cancer risk (see lower arrow, Table 2).
