 [ Symptoms ] i had 2 endometrial biopsy both came negative do i need another biopsy [ Disease ] hi thanks for writing to us well uterine fibroids are noncancerous growths of the uterus that often appear during childbearing years also called leiomyomas or myomas uterine fibroids are not associated with an increased risk of uterine cancer and almost never develop into cancer so please do not worry about cancer and even your biopsies are sufficient to confirm that you are not having any cancer or even not at a risk so simply relax at times fibroids even shrink in menopausal ages so you can continue to monitor it but still you are not at a risk of developing cancer hope this information helps regards
