The DNA colorectal cancer test has several patient-friendly features. An individual can provide a stool specimen in the privacy of their own home by using a special kit that fits on the toilet seat. The DNA test involves no dietary or medication restrictions. Furthermore, in contrast to all invasive screening methods used for colorectal cancer detection, no bowel preparation is needed for the test. The DNA test also detects tumors and polyps throughout the entire colon, whereas sigmoidoscopy, another invasive detection method, inspects only the lower portion of the colon.
Colorectal cancer is largely preventable and curable if detected early.
