How is anorectal cancer diagnosed?

Your physician will perform a physical examination and take a full medical history. He or she will do a digital rectal examination to check for lumps or anything unusual by inserting a lubricated, gloved finger into the lower part of the rectum. Your physician may also use an anoscope or proctoscope – both are short, lighted tubes – to examine the anus and lower rectum, and perform an endoanal or endorectal ultrasound. This test uses sound waves emitted by a probe, or transducer, which is inserted into the rectum and bounces sound waves off tissues to produce an image on a screen. A colonoscopy may be performed to evaluate the rest of the colon. Finally, your doctor may take a biopsy to check for cancer if an area appears abnormal.
