The Mayo Cancer Support Group is threatening to march on Leinster House on Wednesday, November 22nd, if it does not get an assurance that the future of the breast cancer care unit at Mayo General Hospital, Castlebar, is safe. This was decided by a large group of people at a public meeting in Ballina last night. It follows a report of the National Cancer Forum advising the closure and regionalisation of a number of breast cancer units around the State.
