STORY: When Sandy Sagitto was diagnosed with breast cancer she was devastated. (SOUNDBITE) (English) SANDY SAGITTO, BREAST CANCER PATIENT, SAYING: "First thought is that I couldn't believe that I drew that card from the deck. I had no risk factors going in, I had no family history. It wasn't real for a while." But reality set in fast when her doctors said they needed to remove the cancer forming in her body. Sandy took part in a clinical trial to test out a new technology that gives surgeons the ability to visualize cancer cells in real time while they operate. (SOUNDBITE) (English) SANDY SAGITTO, BREAST CANCER PATIENT, SAYING: "Wow, we have headed into the Superman realm. You have the X-Ray vision." Not quite - it's better than X-ray vision, according to Dr. Samuel Achilefu, a professor of radiology at Washington University, who developed the technology. Achilefu says that in a conventional lumpectomy, surgeons rely on scans taken before the procedure to decide how much tissue to remove. He says differentiating between healthy cells and cancer cells is hard, which is why surgeons remove an excess amount of healthy tissue when operating...and even when erring on the side of caution, up to 25 percent of patients need a repeat procedure to remove more cancerous tissue. (SOUNDBITE) (English) DR. SAMUEL ACHILEFU, PROFESSOR OF RADIOLOGY, WASHINGTON UNIVERSITY, SAYING: "The primary goal of the technology is to make sure that the surgeon does not operate in the blind, it's to make the cancer cells light up like Christmas trees." The system works by first injecting the patient with a cancer-targeting dye that attaches to abnormal cells. Then a near infrared light is beamed on the target area which allows a surgeon wearing specialized glasses to see cancer cells glowing. (SOUNDBITE) (English) DR. SAMUEL ACHILEFU, PROFESSOR OF RADIOLOGY, WASHINGTON UNIVERSITY, SAYING: "What this does is conserve the healthy tissue and only go after the ones that are abnormal." Currently the cancer glasses are being trialed on skin and breast cancer patients, but Dr. Achilefu says they could be used to visualize and remove a wide range of cancers. He says lighting up cancer means a brighter future for people diagnosed with the deadly disease.
