"For the last six months it's been 'what if?' What if they had treated me earlier?"

Ronny Andrews, 64, from Cardiff, had a tumour on his liver discovered in January 2017, but it was not until September he finally had chemotherapy.

Cardiff and Vale University Health Board has apologised and said his cancer had been difficult to diagnose.
