Cancer staging manual added to this site

I've added a Cancer Staging Manual with a link to the RCR guidelines and, for a start, pages for lung, renal and prostate cancer, with details of TNM staging and other things I've found useful. These are things I've found difficult to remember, and I've posted them here to save myself the trouble of hunting around for books etc.
You can get to the manual from the 'Protocols and Guidelines' page, or by clicking here.
