What you can do is to add the words, "Prostate Cancer" to the start of all your search requests and that should ensure that most (likely all) of the hits will be in this forum. For example if you want to look for IGRT in this forum enter the following in the search box:
Prostate Cancer IGRT
That should keep the non-PC forums out of the results.
All the best,
