Stomach cancer survival rates up 20% at Cardiff hospital

Doctors say the proportion of people surviving surgery for cancers of the stomach and oesophagus has increased since centralise treatment at a single hospital.

Patients in south east Wales have been sent to Cardiff's University Hospital of Wales for surgery with survival rates improving by 20% since 2010.

It comes as a debate is under way about centralising more NHS services.

Leading clinician Prof Wyn Lewis explains some of the benefits of the scheme to BBC Wales health correspondent Owain Clarke while patient Jan Skwarczek, 57, from Blackwood, believes he had the best care when he was treated for cancer of the oesophagus.
