Japanese biotech firm Hirotsu Bio Science has genetically modified a type of worm to react to the urine of people with pancreatic cancer, which is notoriously difficult to detect early.

Scientists have long known that the bodily fluids of cancer patients smell different to those of healthy people, with dogs trained to detect the disease in breath or urine samples.

The Tokyo-based firm has already used the worms to detect cancer in screening tests, though without specifying which type. He is hopeful it could help boost cancer detection rates in Japan, which like many countries has seen screening rates drop during the pandemic as people avoided medical visits. Hirotsu and Osaka University detailed C. elegans' cancer-detecting skills in a joint study published earlier this year in the peer-reviewed journal "Oncotarget".
