For 13 years, doctors, nurses and midwives from across Cwm Taf have trained volunteer health workers and motorbike ambulance drivers to save lives in a region of eastern Uganda called Mbale through the charity PONT.
Bereaved couple Kieve Lenihan and Geraint Harvard wanted to do something positive in memory of their baby boy Macs who was born in April 2017.
Macmillan Cancer Support and Cwm Taf University Health Board are planning to build a new £6.75m specialist care unit near Llantrisant.
The charity and the health board have applied for planning permission to develop the state-of-the-art unit at Royal Glamorgan Hospital.
If the plans are approved, Macmillan would contribute £5m towards the unit making it their biggest single investment in Wales.
