In theory an ultrasound-guided biopsy using a very fine Bettocchi forceps could be used instead of hysteroscopy- guided biopsies of the endometrium. The technique of ultrasound-guided biopsy is ubiquitous when used elsewhere in the body. It is frequently used to provide histological diagnosis of pelvic masses, (presumed ovarian origin), both abdominally (scanning of the tummy) and transvaginally (internally). Potentially ultrasound guided biopsies could be used as a cheaper, faster and less painful alternative to a hysteroscopy directed biopsies. This pilot study will be the first to assess the diagnostic ability of ultrasound guided biopsy in the assessment of women with suspected endometrial cancer.
