Washington: Scientists claimed to have developed a simple blood test that can accurately detect the beginning stages of breast and lung cancer in just an hour. Researchers from the Kansas State University developed the test that can detect cancer even before symptoms like coughing and weight loss start. The test works by detecting increased enzyme activity in the body. Iron nanoparticles coated with amino acids and a dye are introduced to small amounts of blood or urine from a patient. The amino acids and dye interact with enzymes in the patient`s urine or blood sample. Each type of cancer produces a specific enzyme pattern, or signature, that can be identified by doctors. "These enzyme patterns can also help distinguish between cancer and an infection or other diseases that commonly occur in the human body," researcher Stefan Bossmann said.
