Researchers Develop Blood Test That Detects Early Stages Of Lung, Breast Cancer

9/26/2012 11:42 PM ET

A simple blood test that can accurately detect early stages of breast cancer and non-small cell lung cancer in humans in roughly one hour has been developed by researchers at Kansas State University.

Being an easy-to-do, noninvasive test, this could benefit those classified as at-risk for cancer, such as heavy smokers and people who have a family history of cancer the most, say the researchers.

To the blood or urine sample taken from a patient, iron nanoparticles coated with amino acids and a dye are added. The amino acids and dye interact with enzymes in the patient's urine or blood sample, producing a specific enzyme pattern, or signature. These enzyme patterns can help doctors identify and distinguish between cancer and an infection or other diseases that commonly occur in the human body.

The test showed a 95 percent success rate in detecting cancer in participants, including those with breast cancer in stages 0 and 1 and those with lung cancer in stages 1 and 2. The researchers plan to begin the tests detecting for pancreatic cancer in October and for triple-negative breast cancer this fall.
