Cure Research for Colorectal cancer


Research discussion: Researchers are looking at two new screening tests for colorectal cancer, both of which detect polyps and cancers early. One test is called a virtual colonoscopy. A small tube is placed inside the rectum for less than 5 minutes (with a traditional colonoscopy, this process takes longer). Images are recorded and put into a computer using computerized axial tomography (CAT or CT) scan or magnetic resonance imaging (MRI or MR). The technician then looks at these recorded images to explore the rectum and colon for polyps and cancers. The other test is a stool test (like the FOBT), that looks for DNA, or genetic material, in the stool. Early data suggest that this stool test may be very accurate in picking up any problems, polyps, and cancers.1

A large-scale study, known as the PLCO (Prostate, Lung, Colorectal, and Ovarian) Cancer Screening Trial, is currently evaluating the usefulness of a blood test for the tumor marker known as CA-125 and a test called transvaginal ultrasound for ovarian cancer screening. 2
