Is IMRT Along With Lupron A Safe Procedure To Treat Gleason 7 Prostate Cancer?

I m a retired physician w/Gleason 7 dx 8 mos ago, elected for IMRT and was given 30mg Lupron IM in addition. Who allowed this poison onto the market? 230 gm of lead to the mid brain would have a much more gentle way to go. If there s recurrence, I will quietly die with no mention of hormonal therapy ever again!!!!!!!!!!!!!!!!
