The Health Minister Mary Harney has said the possibility of using St Luke's Hospital in Dublin to provide palliative care is being looked at.
Under new Government plans cancer treatments will be transferred from the Rathgar Hospital to St James Hospital and Beaumont Hospital by 2014.
The facility has been caring for cancer patients from all over Ireland for more than 50 years.
An Oireachtas Committee has heard that there are genuine fears about what the site will be used for.
But Minister Harney says it will be definitely be used for public health purposes.
