No studies have shown that screening by transvaginal ultrasound (TVU) lowers the number of deaths caused by endometrial cancer.
Transvaginal ultrasound (TVU) is a procedure used to examine the vagina, uterus, fallopian tubes, and bladder. It is also called endovaginal ultrasound. An ultrasound transducer (probe) is inserted into the vagina and used to bounce high-energy sound waves (ultrasound) off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. The
doctor can identify tumors by looking at the sonogram.

TVU is commonly
used to examine women who have abnormal vaginal bleeding. For women who have or are at risk for hereditary non-polyposis colon cancer, experts suggest yearly screening with transvaginal ultrasound, beginning as early as age 25.
The use of tamoxifen to treat or prevent breast cancer increases the risk of endometrial cancer. TVU is not useful in screening for endometrial cancer in women who take tamoxifen but do not have any symptoms of endometrial cancer. In women taking tamoxifen, TVU should be used in those who have vaginal bleeding.
