Im not sure where you live, but i know that quebec canada has it and also now the Juravinski cancer clinic in hamilton, Ontario. I have read up on it and it is a robotic radiosurgery designed to treat tumors using radiation therapy within sub- millimeter accuracy.
I believe that is definatly something to get more informed about due to the advances of all types of cancer research.
you can read more on this if you look up the cancer clinic that i have posted.
