A research study has shown that getting genomic test results within days rather than weeks lead to better, more personalised care for more than half of children in the study newly diagnosed with cancer. NHS England is now supporting a national trial of rapid whole genome sequencing (WGS).
In the study, which took place at Addenbrooke's Hospital, faster WGS reduced the average wait for results from six weeks to three days. Having results sooner could enable earlier diagnoses, more targeted treatments and, in some cases, help avoid unnecessary treatments. Read about the study.

Oliver's story, as told by his mum Sara
Oliver is one of the children who has benefited from rapid whole genome sequencing
After Oliver’s initial diagnosis of his tumour at just six weeks old, we began preparing for chemotherapy to shrink the tumour before it could be surgically removed. We were due to be transferred to Birmingham Children’s Hospital by the end of August 2022, when Oliver would have been just eight weeks old. However, the results of his whole genome sequencing changed everything. We had been told that the tumour was a myofibroma (a rare, benign non-cancerous tumour) and that it did not require any further medical intervention. A huge wave of relief washed over us. We continued to attend regular follow-up appointments at Addenbrooke’s Ultrasound Unit and PDU, where we watched the tumour gradually shrink all on its own.

It is hard to believe how far we have come in four years. From the uncertainty and fear of those early weeks to watching Oliver grow into the happy, loving little boy he is today, we feel incredibly grateful for every day with him.
Sara, Oliver's mum
Today Oliver is a happy, cheeky four-year-old who is kind and caring to everyone he meets. He started Reception this September and is loving every minute of it. His favourite things are Paw Patrol, police cars, ambulances, planes and helicopters. He wants to be a pilot for a rescue helicopter when he grows up. He became a big brother in August 2025 and absolutely loves it, taking such good care of his little brother. He also loves going on bike rides and has recently started swimming lessons.
