"delay in supply of chemotherapy drugs to treat bone cancer - Queens Romford"

my mother has been having treatment for bone cancer for sometime and has been told the relevance of having it every 28 days is the best regime for her. NOW it has been two weeks overdue, due to apparently changing suppliers and now this new hospital has NO stock.She cannot take the tablet form of this drug, it makes her really ill, so has the intravenous form. She now is suffering from bones hurting all over her body and still no idea when she will receive the treatment she deserves.
