Scientists have been trying to find a quick, noninvasive cancer-screening test for years. Most doctors now rely on blood tests to detect cancer--and usually only if they suspect you have the disease. Even then, it can take as long as two weeks to get results back.
That could be changing soon. Researchers from the University of California at Los Angeles announced at a conference that they've developed a new test that can detect cancer in a single drop of saliva. With just one mouth swab, doctors would be able to detect traces of cancer cells in 10 minutes. Quick results would mean faster treatment, which could be life-saving for such types of deadly conditions as pancreatic cancer.
The test, which will cost $22, could be done at the doctor's office, at a drugstore, or even at home. And the scientists behind it believe it could be used to screen for ALL cancers, not just one kind.
Right now, the test is being used in clinical trials in China, but researchers hope to roll it out in Europe and later the U.S. in a year or so.
