[00:00.100] From VOA Learning English,
[00:02.060] this is the Health Report.
[00:04.900] Bladder cancer is the ninth most common cancer in the world,
[00:10.440] an estimated 12 million new cases are found every year.
[00:15.920] Now, researchers say they have developed a "scent device"
[00:20.750] that can identify the disease.
[00:24.480] The device is called the OdoReader,
[00:27.270] it has a sensor that finds chemicals
[00:30.560] in the gases released by urine.
[00:34.200] The device takes about 30 minutes
[00:37.530] to analyze the odors in a urine sample,
[00:40.870] to find if a person has bladder cancer.
[00:44.810] The Institute of Biosensor Technology at the University of
[00:50.390] the West of England in Bristol developed the device.
[00:55.170] Chris Probert at the University of Liverpool
[00:59.150] was part of a team that tested it.
[01:02.640] Mr Probert says the results are highly accurate.
[01:07.680] "This data set is very strong: 96-100 percent accuracy.
[01:12.460] We think we are right for the next study
[01:15.690] to show that it is reproducible and then, hopefully,
[01:19.220] we can talk to industry about making a box
[01:21.970] that people can buy for use in surgeries and hospitals."
[01:25.400] Researchers tested the OdoReader on 98 urine samples.
[01:30.990] 24 of them were from patients known to have bladder cancer,
[01:36.510] 74 were from people who had bladder infections,
[01:42.580] but not bladder cancer.
[01:45.150] The device identified everyone of the patients who had bladder cancer.
[01:51.880] Mr Probert says researchers in other labs
[01:56.710] are developing sniffing devices to diagnose stomach cancer,
[02:02.540] another common disease worldwide.
[02:06.770] Researchers say the OdoReader is like a dog's nose.
[02:11.960] An earlier study showed that dogs could be trained
[02:15.890] to detect bladder cancer based on the odor of urine.
[02:21.320] However, the dog's noses was not nearly as reliable as the new device.
[02:28.290] Mr Probert says the scent device could someday be used
[02:33.420] to monitor the health of workers in industries
[02:37.010] like rubber and insulation manufacturing.
[02:40.450] "There's quite a burden of cancer in those employees.
[02:43.400] And so, occupational health in those places of work
[02:47.780] could help their employees by taking a urine sample,
[02:51.710] much as they are doing now
[02:53.450] but with much more accuracy with our machine."
[02:56.300] Bladder cancer is now found by looking for the blood in the urine.
[03:00.730] Mr Probert says researchers have not yet identified
[03:05.560] which gases in urine make the scent unique to bladder cancer.
[03:12.080] But he says they are working on that.
[03:15.670] They are also working on other odor reading devices
[03:19.910] to diagnose other cancers, including those of the uterus and colon.
[03:26.380] The journal PLoS ONE, from the Public Library of Science
[03:31.810] published an article by Chris Probert and his colleagues on the OdoReader.
[03:38.390] And that's the Health Report from VOA Learning English.
