Nyrsys - rydym yn dibynnu ar y dynion a menywod ymroddedig yma i ofalu amdanom ni o ddechrau ein bywydau tan y diwedd. Ond gydag un mewn tri nyrs yn gadael y swydd, mae 'na straen ar y nyrsys sydd ar ôl yn ysbytai Cymru. Mewn cyfres newydd sbon, cawn glywed gan nyrsys mwyaf profiadol y wlad, a'r rhai sydd newydd ddechrau ar eu gyrfa, am eu profiadau. Y tro hwn, awn i Ganolfan Ganser Felindre, Caerdydd ac Ysbyty Llwynhelyg, Hwlffordd, i weld y gwaith da.
Nurses - we rely on these dedicated men and women to take care of us from the beginning of our lives to the end. However, with one in three nurses leaving the post, there is a strain on the remaining nurse in Welsh hospitals. In a brand-new series, we will hear from the country's most experienced nurses and those who are new to the career about their experiences. This time, we visit Velindre Cancer Centre in Cardiff and Withybush Hospital, Haverfordwest, to see their good work.
