The charity Cancer Research UK says it spent £22m last year alone at its Paterson Building in Manchester looking for a cure for cancer.
A spokeswoman said they're awaiting further information about the extent of the damage caused by today's fire.
“The fire broke out in the roof of the Cancer Research UK Manchester Institute which adjoins The Christie on Wilmslow Road. All staff were safely evacuated.
“We are currently awaiting further information from the emergency services about the extent of the damage caused by the fire which broke out this morning.
“The Cancer Research UK Manchester Institute is a leading cancer research institute, based within The University of Manchester which is core funded by Cancer Research UK.
“Last year, Cancer Research UK spent around £22million on research carried out in Manchester.
"Research spans the whole spectrum of cancer research, and also focuses on some hard-to-treat cancers, such as pancreatic and lung cancer.”
Manchester Fire service said the number of fire engines at the scene has been increased to 12, with two aerial platforms also assisting.
No buildings containing patients were evacuated, although nearby offices were.
