A major advance in prostate cancer research could help early detection.
In conventional biopsies, doctors insert a needle into the prostate and take up to 24 random tissue samples.
Now there is a new type of biopsy, one that is far more precise.
First, patients get an MRI that pinpoints the subtle differences between normal and cancerous tissue.
Then, those MRI images are superimposed over the live images of the prostate done during the biopsy so the doctor can be sure he's biopsying the right area.
However, doctors recommend that men get an exam as well as a PSA test.
