A large study, known as the study of early detection of cancer of the Prostate, Lung, Colorectal, and Ovarian, or PLCO trial, seeks to determine whether certain evidence will reduce the number of deaths from these cancers.?The PLCO trial is currently evaluating the utility of three methods to detect ovarian cancer.?One is a blood test that measures the level CA-125, a substance called tumor marker, found in the blood often in quantities greater than normal in women with ovarian cancer.?This study is also evaluating the effectiveness of a physical examination of the ovaries and a test called a transvaginal ultrasound to detect early disease.?Transvaginal ultrasound, also known as DVT, is a procedure used to examine the vagina, uterus, fallopian tubes, and bladder.?An instrument is inserted into the vagina, the sound waves vibrate the organs inside the pelvic area.?These sound waves produce echoes, which uses the computer to create a picture called a sonogram.
