I too have had external beam radiation along with eighteen months of lupron depot hormone therapy. My Gleason score is 7,(3+4) and my oncologist tells me I am in the low end/high risk category due to core sample results from my biopsy. He has given me a fairly positive prognosis. Overall, I am feeling pretty good but the EBR and lupron depot treatments have not been without side affects. Unpleassnt but manageable. I too questioned whether I could go with just EBR but doing so was not recommended. Based on my urologist's assessment and that of my radiation oncologist I am feeling fairly confident about the recommended course of treatment for my PC. Time will tell.🤷‍♂️
