but also hype
Mr Steele commented: “My colleagues and I have been so impressed by the initial investigations by Medical Detection Dogs into prostate cancer screening using dogs.
“The current PSA and Free-to-Total tests are the best we have right now, but they leave a great deal of room for improvement. We need a testing method that is quick, preferably non-invasive and most importantly reliable to encourage men to come and be tested.
“In their training trials, Medical Detection Dogs have achieved 93 per cent reliability and this has been supported by the recent study by Italian scientists who have recorded 98 per cent reliability.
“If they can prove in this study that dogs are reliable at detecting cancer then we will have the evidence we need to offer sample screening by dogs as an optional test in our cancer clinic.
“We should not miss this opportunity to save thousands of lives.”
