The LDR is a 5 - 8 week, 5 days a week treatment. It's not Proton though. One of the Oncologists is recommending that I do the shorter 5 week LDR and then do the newer version of the HDR where you are put under and these long catheters are inserted through the skin into the prostate at several points. Then they wake you and take you elsewhere and at a certain point they hook you up to this machine that introduces temporary high dose radioactive seeds (not permanent) directly into the Prostate.

There are so many side effects, not to mention the invasiveness of the procedure, that I am considering just telling them I would rather go with the longer term LDR alone.
