A “breakthrough” test that uses dried blood samples could detect prostate cancer in 15 minutes or less, scientists believe. Researchers at Aston University have developed a new method that analyses crystal-like structures in dehydrated blood. Professor Igor Meglinski, from the university’s Aston Institute of Photonic Technologies, said the non-invasive technique can detect prostate cancer before symptoms appear with up to 90% accuracy. He said: “This breakthrough opens new avenues for cancer diagnosis and monitoring, representing a substantial leap forward in personalised medicine and oncology…
