Urine odour test for Bladder Cancer.

UK scientists have made a device that can smell bladder cancer in urine samples.



It uses a sensor to detect gaseous chemicals that are given off it cancer cells are present. Early trials show the tests give accurate results more than nine times in 10. Experts say more studies are needed to perfect the tests before it can become widely available.
Each year around 10,000 people in the UK are diagnosed with bladder cancer.
Doctors have been searching for ways to spot this cancer at an earlier stage when it is more treatable, and many have been interested in odours in urine, since past work suggests dogs can be trained to recognise  the sent of cancer.
Prof Chris Probert, from Liverpool University, and Prof Norman Radcliffe, of the University of the West of England, say their new device can read cancer smells. It reads the gases that chemicals in the urine can give off when the sample is heated, said Prof Radcliffe.
This latest method is still at an early stage of development, and needs to be tried out on a much larger set of samples, including samples from both women and men.
The researchers say that the test would be around 96% accurate in practice and their findings are only based on a relatively small number of samples, taken only from men. But it is another promising step towards detecting bladder cancer from a urine sample, something that would ultimately provide a less invasive means of diagnosing the disease.
