A man serving a life sentence at Norwich Prison died from natural causes at the Norfolk and Norwich University Hospital, an inquest heard.
Trevor Lilley, 61, was transferred to the hospital from prison on October 25, 2012, and died on October 30.
Today's Norwich inquest heard Mr Lilley was convicted of attempted murder in December 2008.
In October 2012, tests indicated he had liver cancer, and he was transferred from Wayland prison to the older prisoners' unit at Norwich.
The cause of death was given as pulmonary oedema due to pericardial effusion, with cirrhosis of the liver caused by hepatitis C a contributory factor.
Norfolk coroner Jacqueline Lake concluded that Mr Lilley died from natural causes.
