Leukaemia Research has changed its name to Leukaemia & Lymphoma Research in a rebrand designed to extend its reach and increase its income.
The charity said its revenue had fallen by 25 per cent since the recession began and the new name was designed to give the charity a more inclusive remit.
It hopes the new name, which coincides with its 50th anniversary, will reach all blood cancer patients, including those with lymphoma and myeloma as well as those with leukaemia.
The charity said it needed to raise £120m over the next five years in order to continue its planned research programme.
Cathy Gilman, the charity's chief executive, said: "When we began in 1960, our main focus was to cure childhood leukaemia. With a better understanding of blood cancer, we now aim to save the lives of all blood cancer patients.
"Our change of name will help us to communicate the breadth of our work better and to support more patients than ever before."
