Can Bladder Cancer be Detected by Scent?

Friday, July 19th, 2013

logo1267406_mdPLOS ONE reports that researchers have developed a new “scent device” called the ODOREADER that may prove to be a reliable way to sniff out cancer in patients urine before it becomes a serious problem. Bladder cancer kills more than 15,000 Americans each years and it is expected to cause about 73,000 new cases in 2013. If caught early it can be treated effectively but currently there are no early screening methods other than diagnosis through urine tests at the stage when it starts to becomeĀ  a problem .At that stage there is usually blood in the urine, frequent or painful urination, and back and pelvic pain as the cancer inva=des the cells lining the inside of the bladder. Although there are screening tests for risk of breast and ovarian cancers such as the BRAC nbiomarker, there currently is no reliable biomarkers or measurable molecular signs of a disease that is available for screening bladder cancer. But the ODOREADER may solve that. Following up on research that showed dogs could successfully sniff out bladder cancer researchers speculated that dogs were picking up the scent of certain gasses emitted by the urine and subsequently built a device that contains a sensor that can analyze gases and create a readout of the chemicals found in the urine within 30 minutes.

The device was tested on 24 samples taken from patients with confirmed cases of bladder cancer and 74 samples from patients who had urological symptoms, but no confirmed cancer. The ODOREADER correctly picked 100% of the cancer patients. Although the results are promising there is more work to be done.
