Video Transcript: prostate cancer diagnosis

 

For the patient who is suspected of suffering from prostate cancer – there are several steps to the diagnosis

 

Either we can do a urinary test looking at a gene product that is fairly specifically secreted by prostate cancers called a PCA3 test and/or we can screen the patient’s pelvis and prostate by one of several means.

 

The commonest is transrectal ultrasound which gives us a clear picture of the prostate and may well show abnormalities.

 

Another screening method is MRI scan.

 

However once a suspicion has been raised by one of the methods – PSA or scans, then the definitive diagnosis is made by biopsy.

 

Biopsy is usually performed by a needle approach under ultrasound control, transrectally by taking cores from each of the four quadrants of the prostate.
