![]() FDA panel backs non- invasive colon cancer screening alternative. A panel of Food and Drug Administration (FDA) advisers has voted to endorse an experimental stool test that uses DNA to detect colon cancer and precancerous growths. The FDA's committee of genetic experts voted 1. Get Consumer Updates by email. Keytruda shrank tumors in some patients with advanced disease. Exact Sciences' Cologuard test outweigh its risks. The vote amounts to a recommendation for the FDA to approve the test from Exact Sciences of Madison, Wis. The agency is not required to follow the panel's advice, but often does. Conroy, chairman and chief executive of Exact Sciences, said in a statement. That appears to make it a more effective option than the FIT test (which tends to be 7. Not all cancers bleed to the point that an FIT can pick them up. The same goes for polyps that are large enough and might turn into cancer. Cologuard and other DNA tests in development detect minute genetic changes associated with cancer cells in the colon. On Wednesday, the same FDA panel of experts voted 5- 4, with one abstention, that the benefits of the Epi pro. Colon kit from Epigenomics outweigh the risks. That tests blood samples, not stool. Approving such new tests could reshuffle current practice. The FDA staff's review of Cologuard, released earlier this week, suggests Cologuard would require additional follow- up studies to see how accurately it performs over several years. Current federal guidelines recommend traditional blood stool samples every year for patients between ages 5. It's unclear how often Cologuard would need to be used. It's expected to cost significantly more than blood stool tests, which run about $2. However, Cologuard also returned more false positives, CBS News chief medical correspondent Dr. Jon La. Pook pointed out last week, reporting growths when none were present. So clearly they're going to have perfect this test a little bit more. Deaths from the disease have been declining for more than two decades as screenings have increased. Colonoscopy remains the most accurate test, but many adults are reluctant to undergo the invasive procedure. Freezing Fat: FDA Green Lights Weight- Loss Treatment Zeltiq. If you can't diet or exercise it off, you can now try to freeze or zap it off. The Food and Drug Administration gave the green light for new weight loss treatments: one that freezes fat cells and another that uses a low- energy laser to shrink them. Cleared last week by the FDA as a body contouring treatment, it uses a gel patch attached to a machine that freezes unwanted fat cells, causing them to self- destruct and get re- absorbed into the body over several months. But doctors found that the device worked in the battle of the bulge as well. The fat- freezing device has been used . It's manufacturers have solid scientific evidence to support its effectiveness in freezing on average 2. It's mostly for people of normal body weight with just a few nagging trouble spots. But unlike liposuction, these treatments are non- invasive, meaning there's virtually no down time and very little physical risks. But unlike liposuction, these treatments are non- invasive, meaning there's virtually no down time and very little physical risks. The drug shows promise: Researchers found that clinical trial participants began losing weight four weeks after starting the drug regimen and lost an average of 6. Some have embarrassing gastrointestinal side effects and doctors have continuously stressed that pills and lasers are never meant to replace old- fashioned diet and exercise.
