Small 'bubble-like' particles released by cells into the bloodstream may help us detect early-stage cancers, thanks to the proteins they contain, according to Australian research. The researchers compared the proteins in these particles from healthy cells and cancer cells and found a pattern of four proteins linked to cancer. They used this information to develop a test to pick up the same four proteins in cancer samples. When they checked their test's performance on samples from patients with nine different types of cancer or from healthy people, they found the test could differentiate healthy samples from cancer samples with a high level of accuracy. They then tested it on 68 samples from patients suspected of having lung cancer, and found that it could differentiate between harmless lung changes and early-stage lung cancer.
