@rcs You may not be Crazy for not doing Lupron, but you will be presenting a larger cancer to be the target of that beam.. I went to Mayo MN.. they recommended the shot and then we gave it 2 months to work in making the problem smaller.. How old are you? Yes, the 20 sessions makes you very tired.. If you do not take the shot will you have to have more than 20 sessions..? well, the actual radiation session from the time you walk in the door until you walk back out is usually less than 30 minutes... but getting there, waiting for the machine to clear is another matter.. have you been tattooed at this point? Aiming is really important..
