SIR - June 10 sees the Worcester Race For Life. I wonder how many entrants and supporters of this event are aware of how their donations are actually spent?

Organisers Cancer Research UK fund animal research, which I believe has not only contributed little to the development of cures for cancer sufferers but has, in fact, held back medical progress of treatments for human cancer by diverting funds away from more scientifically valid tests.

I would ask those who wish to contribute towards the fight against cancer and other diseases to look at alternative charities (such as the Dr Hadwen Trust) which funds more humane and, in my view, effective research.
