Timm, 38, has been diagnosed with acute myeloid leukaemia (AML) for the second time. His only hope now is a blood stem cell transplant from a stranger.

It costs DKMS £40 to register each potential lifesaver. We rely on the generosity of our supporters to cover this cost, and register more potential matches for people with blood cancer, like Timm.

Please help us to find more lifesavers by donating today.
