    At-home test for colon cancer
    집에서 하는 결장암 검사

    This week we're taking a look at medical screenings, some important tests you need and some you might not. Tonight we look at a new test for colon cancer, the second leading cause of cancer-related deaths. It's a cancer that can be caught early and treated successfully, if you get a colonoscopy. But a third of Americans who should get one, don't. 
    Our Rehema Ellis looks into a new test that's easier and less invasive at home and could save your life. As the sun rises over Marlboro, Massachusetts, Dorothy O'Shea is grateful to be alive. When she turned 50 last year, she knew doctors recommended having a colonoscopy, but like more than 20 million Americans, 50 and older, she just didn't. 
    "I've heard horrible, horrible things about the prep for the colonoscopy. And I just didn't see the cost-benefit ratio." The process includes fasting, laxatives, anesthesia, and the invasive screening procedure itself. ("We're looking for the polyp.") But Dr. Mark Schaefer, one of the world's top colon cancer specialists, is prescribing a new option for some patients that can be done at home, not as thorough as a colonoscopy, but better than nothing. 
    "The main thing is that the best test is the one that gets done." "So, the home screening kit comes in the mail?" "Right." It's called Cologuard and it's the first FDA approved test of its kind. "What do you have to do before you do this test?" "Nothing. You just have to do your business with this container underneath, and then you just close the lid after you put the buffer in, and you're done."
    Then you ship the sample to a lab, which looks for blood and DNA associated with colon cancer. In a study of 10,000 patients, Cologuard detected 92% of colon cancers. It costs about $650, and it's covered by about a quarter of private insurers. 
    "Cologuard basically saved my life." Dorothy's doctor convinced her to try it. When the results were positive, she had a traditional colonoscopy to confirm. "I just kept saying over and over in my head, 'I can't believe I have cancer.'" Or at least she did. After surgery, Dorothy's cancer-free for now and running strong. Rehema Ellis, NBC News, New York.
