This makes early diagnosis tricky, though doing so could lead to far better outcomes for patients. Scientists at Japan's Nagoya University have demonstrated how this could be achieved through a simple urine test, which has shown high accuracy in early experiments.Along with blood tests, urine tests are shaping as an exciting technology when it comes to non-invasive and efficient cancer diagnosis. By scanning these fluid samples for biomarkers that correlate with the disease, scientists have shown how they might be able to detect cancer long before the typical clinical symptoms appear. These studies have shown particular promise when it comes to cancers of the bladder, prostate, pancreas and even the lungs.
