A new type of test that uses complex sugars to detect prostate cancer earlier and with greater accuracy is being developed by researchers at the University of Birmingham. The test works by identifying sugars, known as glycans, in blood. These sugars are attached to protein molecules called PSA and are known to undergo distinct but subtle changes when cancer is present in the body. Read the article.
