I don’t know if the chances of lesion being positive. On digital rectal exam was prostate enlarged? PSA pattern? age? Your overall health and lifestyle? all these situations create could tilt the opinion but that’s still only a opinion really..
The timing of the process can be stressful as I have been there. Research no dumb questions be your own advocate.. many people do have extreme side effects to Eligard/Lupron myself just a few hot flashes currently in 6th month. With last week of 8 weeks radiation treatments experiencing mild fatigue and that could just be the 4am wake up necessary for daily travel to clinic..
hopefully you and your journey never have the need for either treatment
