JoshuaInNippon writes: Japanese researchers at Kanazawa University announced on Nov. 19th that they have discovered a way to detect cancer in the digestive system using a simple and relatively cheap blood test with a 90 percent accuracy rate. The test is apparently done by analyzing RNA and looking for abnormalities in more than 800 specific genes believed to be caused by the presence of cancer. Previous tests for stomach, colon, pancreas, and other such cancers, have only yielded accuracy rates of less than 30 percent. The lead researcher has started a venture company, and hopes to have the test in hospitals in Japan as early as the end of next year. One can only wonder when all forms of cancer will be easily detectable at early stages with such simple and (relatively) pain free testing.
