A family from Cardiff is paying £75,000 for a cancer treatment which is available for free in England.
Elaine May has malignant melanomas, but doctors think a new drug could help extend her life.
The treatment hasn't been approved yet by the health watchdog NICE so it is not available on the NHS.
However, if Elaine lived in England she could get funding for the treatment from the Cancer Drugs Fund, which helps English patients in such circumstances.
As there is no equivalent fund in Wales, Elaine and her husband Geoff are having to pay for the drug themselves from their life savings.
It's a subject that has angered the family. They believe there should be the same system for funding drugs in Wales and England.
But the Health Minister for Wales Lesley Griffiths believes the system in place in Wales is better than in England, as money is not diverted from other areas of the NHS.
The Health Minister added that the system was reassessed in the Spring and that the situation is being constantly monitored.
