to be able to direct the radiation to a precise location.\u00A0 A concern has been that - since the prostate bed is essentially the absence of something in being a fossa - with movement between radiation visits, for example walking, the location of your prostate bed could vary from treatment to treatment.\u00A0 Movement in this area could result in parts of the region receiving inadequate radiation, or in contrast, too much radiation.\u00A0 Thus far studies have not shown that the area moves in a way that could significantly interfere with treatment.&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;&amp;lt;sub&amp;gt;Sources:&amp;lt;/sub&amp;gt;&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;&amp;lt;sub&amp;gt;Barkati, M., Simard, D., Taussky, D., and G.
