New Delhi: Researchers have now developed an electronic nose which can detect prostate cancer by simply smelling urine samples.

Prostate cancer is a type of cancer that only affects men. It tends to develop in men over the age of 50, although cases of early cancer development have also been seen.

Electronic nose comes as a good news as the current methods available for diagnosing prostate cancer in men are quite expensive.

In a new study, the 'eNose' successfully discriminated between prostate cancer and benign prostatic hyperplasia (BPH) by 'sniffing' urine headspace - the space directly above the urine sample.

The heterogeneity of prostate cancer makes it difficult to diagnose and predict tumour progression. Thus, there is a need for novel diagnostic tools.

The eNose was tested on 50 patients who had been diagnosed with prostate cancer confirmed by biopsy, and 15 patients with BPH.

The eNose is a device that consists of a cluster of non-specific sensors.

When the device is exposed to the sample, it produces a profile or a “smell print”.

Results with the eNose confirmed that using urine headspace, the eNose was able to discriminate prostate cancer from BPH, said the study appeared in the Journal Of Urology.
