Cwm Taf University Health Board is the only health board in Wales to share end of life patient advance care plans (ACP) with Welsh Ambulance Service Trust (WAST) control room staff.
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.
More than 1,000 extra patients in the Cwm Taf health board area could be encouraged to take part in screening for bowel cancer by a follow up letter from their GP, researchers found.
