Like Arthur, I also found this fascinating. Exciting too in a way. Especially when considering prostate cancer in UK where every hour one man dies from it.
We all know us men are not good at seeking help from the GP and this procedure, being so simple, could help tremendously.
I also heard an interview on BBC local radio yesterday that explained new and highly accurate non-invasive treatments for prostate cancer.

Many advancements being made these days.
