What percentage of endometrial biopsies are cancerous?
Conclusions: In a postmenopausal woman without vaginal bleeding, if the endometrium measures > 11 mm a biopsy should be considered as the risk of cancer is 6.7%, whereas if the endometrium measures < or = 11 mm a biopsy is not needed as the risk of cancer is extremely low.
Can uterine cancer go undetected?
Some women with endometrial cancer have no symptoms until the disease has spread to other organs. But endometrial cancer is usually diagnosed by the appearance of symptoms — like vaginal bleeding — as the cancer begins to grow.
