- The Cancer Patient Experience Survey is the first of its kind carried out for cancer patients in Wales
- 11,000 cancer patients were asked to complete the survey
- 7,352 gave their views
- 89% rated their care as either excellent or very good
Health Minister Mark Drakeford has today published the results of the first ever Cancer Patient Experience Survey produced by the Welsh Government and Macmillan Cancer Support.
The survey reports the views of 7,352 cancer patients in Wales, with 89 per cent of those who responded saying the care they received was either excellent or very good.
However, the results show that some believe that they did not get enough support from locally-based health and social services.
It is also thought that people with rarer forms of cancer are more likely to be less positive about the care they received.
