A new liquid biopsy test using artificial intelligence models could help spot a rare type of bone and soft tissue cancer that predominantly affects children and adolescents. The test is being developed by researchers funded by British charity Cancer Research UK for Ewing sarcoma, a rare cancer with a high risk of spreading that can evade modern scanning techniques.
