RE the letter (LET, June 22) from Jo Tanner entitled No animal tests.' which correctly said that, in spite of many years of research involving animals, cures or effective treatments for diseases such as cancer or Alzheimer's have not been found.

Millions of animals in British laboratories will continue to suffer and die in useless experiments. Why?

As well as causing pain and suffering, animal testing is unsatisfactory because of the difference between people and animals, which can give misleading results.

The way forward is to invest in research to find effective non-animal testing methods.
